Thank you so very much for your encouragement, dear brother in Christ! And thank you, dear sister in Christ, for posting Revelation 5:6!
And I saw in the right hand of him that sat on the throne a book written within and on the backside, sealed with seven seals. And I saw a strong angel proclaiming with a loud voice, Who is worthy to open the book, and to loose the seals thereof? And no man in heaven, nor in earth, neither under the earth, was able to open the book, neither to look thereon. And I wept much, because no man was found worthy to open and to read the book, neither to look thereon.
And one of the elders saith unto me, Weep not: behold, the Lion of the tribe of Juda, the Root of David, hath prevailed to open the book, and to loose the seven seals thereof.
And I beheld, and, lo, in the midst of the throne and of the four beasts, and in the midst of the elders, stood a Lamb as it had been slain, having seven horns and seven eyes, which are the seven Spirits of God sent forth into all the earth. - Revelation 5:1-6
This and the preceding chapter, Revelation 4, are among my most treasured meditations! Thank you for bringing it to the table! Verse 6 underscores the doctrine of the Trinity or more specifically, Who God IS.
The One sitting on the throne in verse 1 and in the previous chapter is Almighty God, El Shaddai.
Christ, who is the Root of David, the Lion of the Tribe of Judah emerges from the bosom of the Father as the Lamb of God.
No man hath seen God at any time; the only begotten Son, which is in the bosom of the Father, he hath declared [him]. - John 1:18
Christ is revealed both as the suffering Lamb and also as the conquering Lion. And the mystery of the throne of David, Judaism and Christianity, is resolved again identifying that Jesus Christ is God.
While the Pharisees were gathered together, Jesus asked them, Saying, What think ye of Christ? whose son is he? They say unto him, [The Son] of David. He saith unto them, How then doth David in spirit call him Lord, saying, The LORD said unto my Lord, Sit thou on my right hand, till I make thine enemies thy footstool?
If David then call him Lord, how is he his son? - Matt 22:41-45
And again,
The LORD hath sworn [in] truth unto David; he will not turn from it; Of the fruit of thy body will I set upon thy throne. - Psalms 132:11
And again,
I Jesus have sent mine angel to testify unto you these things in the churches. I am the root and the offspring of David, [and] the bright and morning star. - Revelation 22:16
And as the Lamb emerges from the bosom of the Father, we see that Jesus Christ has seven horns and seven eyes which are the seven Spirits of God. Thus it reveals again the Trinity, Almighty God is One God in three Persons. The Lamb of God emerges from the bosom of God the Father sending forth the Spirit of God into the world.
But when the Comforter is come, whom I will send unto you from the Father, [even] the Spirit of truth, which proceedeth from the Father, he shall testify of me: - John 15:26
And as we can also see from the passage below, the Spirit, though He indwells each of us Christians individually, is One: Spirit, Spirit of God, Spirit of Christ.
But ye are not in the flesh, but in the Spirit, if so be that the Spirit of God dwell in you. Now if any man have not the Spirit of Christ, he is none of his. – Romans 8:9
The Spirit is no less One by His indwelling than God is by the Persons of the Father, the Son and Holy Spirit. The significance of seven in prophecy - particularly Revelation - is completeness. Seven Spirits, seven horns, seven eyes, seven churches, seven seals and so on. Also the seventh day of Creation is the Sabbath.
And on the seventh day God ended his work which he had made; and he rested on the seventh day from all his work which he had made. And God blessed the seventh day, and sanctified it: because that in it he had rested from all his work which God created and made. - Genesis 2:2-3
Which is also prophecy:
Let no man therefore judge you in meat, or in drink, or in respect of an holyday, or of the new moon, or of the sabbath [days]: Which are a shadow of things to come; but the body [is] of Christ. - Colossians 2:16-17
The horns are dominions. So Christ is the completion, the final cause, in Him all fullness dwells.
I am Alpha and Omega, the beginning and the end, the first and the last. - Rev 22:13
And again,
Who is the image of the invisible God, the firstborn of every creature: For by him were all things created, that are in heaven, and that are in earth, visible and invisible, whether [they be] thrones, or dominions, or principalities, or powers: all things were created by him, and for him: And he is before all things, and by him all things consist. And he is the head of the body, the church: who is the beginning, the firstborn from the dead; that in all [things] he might have the preeminence. For it pleased [the Father] that in him should all fulness dwell; And, having made peace through the blood of his cross, by him to reconcile all things unto himself; by him, [I say], whether [they be] things in earth, or things in heaven.– Colossians 1:15-20
God's Name is I AM.
