True origin in God

 God has no origin, beginning, or creator. In classical monotheistic theology, God is the eternal, uncaused first cause who exists outside of time.

Key Theological Concepts

• No Beginning or Origin: God is unmade and pre-dates all created things. If another being created God, that entity would be the ultimate God, resulting in an endless regress of creators.

• Self-Existence (Aseity): God is self-existent and depends on nothing outside of Himself to exist.

• Beyond Time: Because time is part of the created universe (space, matter, and time), God stands outside of linear time as the "Alpha and Omega".

• The Source of All Things: As stated in the The Gospel Coalition Africa, everything in existence has a beginning that traces back to God, who was already there before all things.

Would you like to explore how different philosophies or biblical passages (such as Exodus 3:14 or Psalm 90:2) explain God's eternal nature?

Exodus 3:14, New International Version, 14 God said to Moses, "I am who I am. This is what you are to say to the Israelites: 'I am has sent me to you.'"

"I Am that I Am" is a common English translation of the Hebrew phrase אֶהְיֶה אֲשֶׁר אֶהְיֶה, which appears in the Hebrew Bible. The phrase is also translated as "I am who I am", "I am that am", "I will become what I choose to become", "I am what I am", "I will be what I will be", "I create what I create", or "I am the Existing One" ...

Revelation , GOD in HIS WORD

 REVELATION 21:1 And I saw a new heaven and a new earth: for the first heaven and the first earth were passed away; and there was no more sea. 

2 And I John saw the holy city, new Jerusalem, coming down from God out of heaven, prepared as a bride adormed for her husband. 

3 And I heard a great voice out of heaven saying, Behold, the tabernade of God is with men, and he will dwell with them, and they shall be his people, and God himself shall be with them, and be their God. 

4 And God shall wipe away all tears from their eyes; and there shall be no more death, neither sorrow, nor crying. neither shall there be any more pain: for the former things are passed away.

God IS His Word John 1:1 

LEADERSHIP  " Now, to refuse that Person that is doing the calling, Christ, no matter if you're Pentecostal, Methodist, Luther, whatever you are, you got to... This age! Nothing against them, not at all, but in this age now you've got to accept (like they did in that age) the Person of Christ which is the Word: 

In the beginning was the Word, and the Word was with God, and the Word was God. 

And the Word was made flesh, and dwelt among us,... ...the same yesterday,... today, and for ever. Hebrews 13:8. 

See, you must accept that Person of Eternal Life!" 

MODERN EVENTS ARE MADE CLEAR BY PROPHECY ...

We're not living in a Pentecostal age; we're living in another age. See? 

We're not living in a Methodist age; we're living in another age. 

We're living on up here to the Bride age, the calling out of the church and getting it together for the rapture. That is the age that we're now living. To my honest opinion that is exactly the truth. 

 And this Book of Revelation is a Book of prophecy.

 There is no such a thing as spiritual death now, to a baptized saint of God. "Though he were dead, yet shall he live. Whosoever liveth and believeth in Me shall never die." All Scripture, It must be fulfilled. See? You can't die. You got Eternal Life. Only thing, the Redeemer has made you recognize it. And you were always that, and that's the reason you see the day you're living in. How many sees it? Raise your hand. See? Thank you. See? The day that we're living in, you recognize it.

"And if you are the Bride, the Bride is a part of the Husband. The only place that you'll ever recognize it, is recognize what part of that Husband (that Word) you are, or you can't recognize being the Bride. 

How many sees that? [congregation says, "Amen."] See? See?

 There is one Bride; not a dozen denominations. But one Bride, that is the Elected out of the earth that is been predestinated to this, the ones who can recognize their place in the Kingdom. 

 I can only teach my types now. Notice. 

Who come out on the new earth with Noah the prophet? Those who went in with him in the ark. That is right. That is who walks out on it. See: Those who went in with Noah, by his message, was the one who walked out upon the new earth after its water baptism. 

 The one who goes in with Lord Jesus Christ now. How do you get into Him? By one Spirit; and He is the Word. You become part of Him. What part of Him are you? 

The Word that's living in this hour, recognizing. 

You'll walk out with Him in the Millennium.

Qualification 

 He was the spoken Word. We who are redeemed is part of Him. Then, if you can recognize! See? 

The Pharisees claimed they were. But, you see my first illustration, they was only that by intellectual. They couldn't recognize the Word when It was made manifest right before them. They said, "This man is a evil spirit." 

Help us, God. If there is one here who isn't just exactly sure of that, Lord, may they receive it just now. 

 I know it's been long, and hot, but, people, we won't always be standing here. I won't always be your pastor. Let's make it sure. "Is there a way, Brother Branham?" 

Yes, become a part of the Word, a part of the Word of today. 

Can't be a part of the Word of Moses' day; that part is done 

made up, that was the feet. We're at the Head now. This is 

Christ. Not the arms time, back in Luther, no. 

This is the Head time. Christ, the Headstone, comes to the Body.

"And then the rest of the dead lived not till the end of the thousand years." Then, at the end of the thousand years, there was a Judgment, showing that Ham was in the ark. And Ham is still there in the remnant. Ones that heard It and rejected It wil have to be judged. 

 Now, grant it, Lord, that we'll not be considered among them, but will be in the call to the Wedding Supper. For we do recognize Jesus among us today: We're going in with Him; out of the world, into Him. Let us walk forth in that City, come out with Him.

Here is what organized religion fails to recognize Regarding the Bible: Every Word that's written in there must come to pass. (They would agree thus far.) 

Everything that's been promised has to come to pass. because It is Jesus Christ in each age. 

Jesus Christ was in Noah; 

It was Jesus Christ in Moses: 

It was Jesus Christ in David: 

It was Jesus Christ in Joseph; 

It's Jesus Christ, the same yesterday, today, and forever. 

He is the living Word. The "I AM." 

He merely changes His form and measure. 

What is His form in this Bride age? 

🔴 COLOSSIANS 1:25-27; Whereof I am made a minister, according to the dispensation of God which is given to me for you, to fulfil the word of God; 

🔴 Even the mystery which hath been hid from ages and from generations, but now is made manifest to his saints: ·

🔴 To whom God would make known what is the riches of the glory of this mystery among the Gentiles; 

· This mystery 

· This mystery - which is 

· which is Christ in you, the hope of glory:

Psalm 119:1

 Psalm 119 is one of the alphabetical, or acrostic*, psalms. 

The first letters of each group of eight verses follow the order of the Hebrew alphabet. 

The twenty-two sections of this psalm thus correspond to the twenty-two letters of the Hebrew alphabet. 

Furthermore, all the verses in a particular section begin with the same Hebrew letter.

[*An acrostic is a poem, puzzle, or text in which specific letters—most commonly the first letter of each line, paragraph, or stanza—spell out a word, message, or the alphabet when read vertically.]

Common Types of Acrostics

• Standard Acrostic: The first letter of each line spells the word or message.
• Telestich: The last letter of each line spells out the hidden word.
• Mesostich: Letters in the middle of each line spell out the message.
• Double Acrostic: Both the first and last letters of each line spell out words.
• Abecedarian: The lines or stanzas begin with consecutive letters of the alphabet (A, B, C...). [1, 2, 3]

Example of a Standard Acrostic

Using the word STAR:

• Sunlight shining bright
• Towering trees above
• All a-glowing bright
• Radiant in the sky

119:1 Blessed are those whose way is perfect,
Who ^awalk in the ¹law of Jehovah.

a. (cross reference) 1 Kings 9:4 And as for you, if you walk before Me, as David your father walked, with a perfect and upright heart by doing according to all that I have commanded you and keep My statutes and My ordinances,

Luke 1:6 And ¹they were both ^2arighteous before God, ^3bwalking in all the commandments and ⁴ordinances of the Lord, ^cblameless.

^1. They were among God's chosen people and had been preserved in the custody of the law in the Old Testament and brought forth by it to be useful to God for the initiation of the gospel in the New Testament.

2a. c-r.:

Luke 1:75; 2:25; Genesis 7:1

This does not contradict Romans 3:20. Here it means to be right, i.e., blameless, in the sight of God according to the Old Testament commandments and ordinances (Luke 2:25; Philippins. 3:6). It does not mean that these righteous ones were not sinful, without sin and sins. They were blameless, but not without blemish. They still needed the unblemished sin and trespass offerings in type (Leviticus 4:28; 5:15) for their propitiation that they might have contact with God.

^{Romans 3:20 Because out of the works of the law no flesh shall be justified before Him; for through the law is the clear knowledge of sin.} c-r.: Galatians 2:16  And knowing that a man is not justified out of works of ^alaw, but through ^1bfaith in Jesus Christ, we also have believed into Christ Jesus that we might be justified out of faith in Christ and not out of the works of law, because out of the works of law ^c no ²flesh will be justified.  Acts 13:39 And from all the things from which you were not able to be justified  by the law of Moses, in this One everyone who believes is justified. Romans 2:13 (For it is not the hearers of the law who are righteous before God, but the doers of the law shall be justified.) Galatians 2:16 And knowing that a man is not justified out of works of law, but through faith in Jesus Christ, we also have believed into Christ Jesus that we might be justified out of faith in Christ and not out of the works of law, because out of the works of law no flesh will be justified. Galatians 3:11 And that by law no one is justified before God is evident because, "The righteous one shall have life and live by faith''; (Lit., in; meaning "in the power of, in virtue of") 

¹ law

~ The word law is used twenty-five times in this psalm 119 (vv. 1, 18, etc.). Psalm 119:1 Blessed are those whose way is perfect, Who walk in the law of Jehovah. Psalm 119:18 Open my eyes that I may behold Wondrous things out of Your law. [Cross reference: Luke 24:45; Acts 16:14. Luke 24:45 Then He ^1aopened their mind to understand the Scriptures; Acts 16:14 And a certain woman named Lydia, a seller of purple-dyed goods from the city of ^aThyatira who ^bworshipped God, was listening, whose heart the ¹Lord ^copened to give heed to the things being spoken by Paul.

c-r.:

Psalm. 119:18; Acts 16:14

Indicating that to understand the Scriptures requires that our mind be opened by the Lord Spirit through His enlightening (Ephesians 1:18).

~ A number of different synonyms for law are also used, including testimony (once, in v. 88), 

~ testimonies (twenty-two times, in vv. 2, 14, etc.), 

~ word (thirty-six times, in vv. 9, 11, etc.), 

~ words (six times, in vv. 57, 103, etc.; cf. Exodus 34:28, lit.), 

~ commandment (once, in v. 96), 

~ commandments (twenty-one times, in vv. 6, 10, etc.), 

~ statutes (twenty-two times, in vv. 5, 8, etc.), 

~ ordinances (seventeen times, in vv. 7, 13, etc.), 

~ judgments (three times, in vv. 75, 120, 137), 

~ and precepts (twenty-one times, in vv. 4, 15, etc.). 

~ All these terms from law to precepts consummate in the way (four times, in vv. 14, 27, 32, 33) or ways (three times, in vv. 3, 15, 37), signifying Christ as the way of God for His people (John 14:6). 

Psalm 119 is a psalm of 176 verses describing Christ, who is the reality of the law, the commandments, the ordinances, the statutes, the precepts, and the judgments.

What is an acrostic?

 

Acrostic Definition

What is an acrostic? Here’s a quick and simple definition:

An acrostic is a piece of writing in which a particular set of letters—typically the first letter of each line, word, or paragraph—spells out a word or phrase with special significance to the text. Acrostics are most commonly written as a form of poetry, but they can also be found in prose or used as word puzzles.

Some additional key details about acrostics:

• While the most common type of acrostic is one formed by the initial letters of each line, there are many different types of acrostics with letters in different positions.
• The word that is spelled out in an acrostic is called the acrostich. The acrostich typically bears a special meaning in relation to the content of the acrostic, such as revealing the name of the poem's subject or the name of its author.
• Acrostic poems may be written in meter or in free verse, with or without rhyme.

Acrostic Pronunciation

Here's how to pronounce acrostic: uh-krahss-tik

Types of Acrostic Poems

In the most common type of acrostic poems, the initial letter of each line forms a word. This type of acrostic is simply called an acrostic.

Roses are red,
Oranges yummy,
Sugar's a sweet,
Elixir in my tummy.

But other types of acrostic, with more specialized locations of the letters that spell out the word or phrase, do have special names:

• Telestich: An acrostic in which the last letters of each line spell a word or message.
• Mesostich: An acrostic in which the middles of words or lines form a word or message.
• Double Acrostic: An acrostic in which words are spelled by both the first and last letters of each line, so that one word can be read vertically down the left side of the poem and another word can be read vertically down the right side of the poem.
• Abecedarian: An acrostic that, instead of spelling a word, spells the alphabet. Chaucer's poem "La Priere de Nostre Dame" is an example of an abecedarian acrostic. This type of acrostic may also be referred to as an abecedarius.

In addition to these named forms, acrostics can be non-standard. For example, some acrostics spell out words using neither the first nor last letters of a line, but rather by emphasizing letters in different places.

Roses are red,
Violets are blue,
Sugar is sweet,
And so are you.

Decoding Acrostics

The level of difficulty in decoding the hidden message of an acrostic varies widely, and that difficulty depends on how carefully the author has hidden it or, conversely, how deliberately he or she has revealed it. In many cases, it's easy to recognize the word being spelled in the acrostic because the important letters are capitalized or bolded and they fall at the beginning of each line. In other cases, the author may have intended for the acrostic to be harder to solve, leading them to insert the important letters more subtly by embedding them somewhere other than the first word of each line or leaving the letters lower-case. Put another way: an acrostic may be a show, in which the author wants you to see it at once, or a puzzle that the author is content to have some people find and other's not.

Acrostics vs. Acronyms

Acrostics are in some ways similar to acronyms, in that both involve the isolation of individual letters to make a new word. Just as a poem might form the acrostich "Rose" from the first letters of its four lines, so is the acronym POTUS made by taking the first letters of "President of the United States." However, acrostics and acronyms are not the same, for two reasons:

• Real words vs. made-up words: Acrostics must form real words or names (or at the very least spell out the letters of the alphabet). In contrast, acronyms can be made up words. For example, POTUS isn't really a word, it's just an acronym that makes it easier to refer to the President of the United States. Acronyms can form real words, such as ACT UP, the acronym for an important activist group of the 1980's that was otherwise known as "AIDS Coalition to Unleash Power," but they don't have to.
• Artistic merit vs. practical use: The more significant difference between acronyms and acrostics is that while acronyms have a practical purpose—whether as a mnemonic or to make it easier to refer to things more quickly—acrostics have been regarded, to varying degrees at different moments in history, as a form of writing with literary value.

Acrostics Through History

The earliest examples of acrostics can be found in the Hebrew Bible. Several passages in the book of Psalms begin with letters of the alphabet, forming an abecedarian acrostic (an acrostic that spells out the entire alphabet). The first examples of non-abecedarian acrostics come from ancient Greece, where the Erythraean Sybil (an oracle from the ancient Greek town of Erythrae) was known to write her prophesies on leaves and arrange them so that the first letters would spell out a word. Later, acrostics were commonly used in medieval literature to encode a secret message—for example, to disclose the name of the poet or the name of the poem's subject, especially in cases where the subject of the poem was a secret lover. Today, however, acrostics have lost some of the literary prestige they once enjoyed in the past. Instead, they are now often considered to be juvenile, or useful primarily as a comedic form.

Acrostic Examples

In the examples below, the letters that form the acrostich (the acrostic's hidden message) are bold.

Acrostic in Lewis Carroll's "Acrostic"

This poem by Lewis Carroll spells out the names of three sisters: Lorina, Alice, and Edith. Alice was purportedly the real-life inspiration for Carroll's book Alice's Adventures in Wonderland.

Little maidens, when you look
On this little story-book,
Reading with attentive eye
Its enticing history,
Never think that hours of play
Are your only HOLIDAY,
And that in a HOUSE of joy
Lessons serve but to annoy:
If in any HOUSE you find
Children of a gentle mind,
Each the others pleasing ever—
Each the others vexing never—
Daily work and pastime daily
In their order taking gaily—
Then be very sure that they
Have a life of HOLIDAY.

Acrostic in Nabokov's "The Vane Sisters"

While acrostics are most often found in poetry, Vladimir Nabokov's short story "The Vane Sisters" contains an example of an acrostic formed with prose. In "The Vane Sisters," a short story which is about a professor who becomes fascinated with acrostics, the first letters of each word in the story's final paragraph spell out the phrase, "Icicles by Cynthia; Meter from me, Sybil." While these words may seem like nonsense if you haven't read the story, they are, in fact, key to interpreting the story's mysterious plot.

I could isolate, consciously, little. Everything seemed blurred, yellow-clouded, yielding nothing tangible. Her inept acrostics, maudlin evasions, theopathies—every recollection formed ripples of mysterious meaning. Everything seemed yellowly blurred, illusive, lost.

Acrostic in Chaucer's "La Priere de Nostre Dame"

Commonly referred to as "Chaucer's ABC's," this poem is an example of the sub-genre of acrostic known as abecedarian poetry, in which the first letters of each stanza spell the alphabet in sequence.

ALMIGHTY and all-merciable Queen,
To whom all this world fleeth for succour...

Bounty so fix'd hath in thy heart his tent,
That well I wot thou wilt my succour be...

Comfort is none, but in you, Lady dear!
For lo! my sin and my confusion...

Acrostic in Blake's "London"

This poem by William Blake puts a special emphasis on the sounds of London's cityscape, such as the cries of the chimneysweeps and the sighs of the soldiers. In the third stanza, the initial letters of each line form an acrostic that spells the word "HEAR," which underscores the speaker's fixation on the sounds in his environment. This is an example of acrostic being used in just one stanza of a poem—the remainder of the poem does not contain acrostics.

How the Chimney-sweepers cry
Every blackning Church appalls,
And the hapless Soldiers sigh
Runs in blood down Palace walls

Acrostic in Cage's "Overpopulation and Art"

John Cage was a hugely influential experimental composer and poet who, toward the end of his life, became interested in writing acrostic poems in which the key letters were placed in the middles of lines instead of at the beginnings—a form known as mesostich poetry. The following excerpt is the beginning of one of the last poems Cage wrote in his lifetime, "Overpopulation and Art." The long mesostich poem, written in free verse, spells out the words of the title, "overpopulation and art," twenty times (the number of letters in the title). The excerpt below shows just one of the twenty cycles of the poem.

Why Do Writers Choose to Write Acrostics?

Acrostics are used to add new dimension to a poem or other text. They can transform straightforward poetry or prose into a word puzzle by enlisting the reader to decode a secret message. In addition, acrostics are often used to spell out names or meanings that are associated with the text but that have not been said outright—this can be used for comedic effect, to tell a secret, or to give supplemental information. Acrostics can also make poems easier to remember or memorize, as their messages can function as mnemonic devices that help a reader to recall the remainder of each line. For this reason, acrostics are commonly used in children's poetry.
