My favorite "proof" scripture of the divinity of Jesus Christ:
Revelation 21:6-7
"And he said unto me, It is done. I am Alpha and Omega, the beginning and the end. I will give unto him that is athirst of the fountain of the water of life freely.
He that overcometh shall inherit all things; and I will be his God, and he shall be my son."
Let's break it down, shall we?
1) Who is the Alpha and Omega in Rev 21:6?
"I am Alpha and Omega, the beginning and the ending, saith the Lord, which is, and which was, and which is to come, the Almighty." - Revelation 1:8
"I was in the Spirit on the Lord's day, and heard behind me a great voice, as of a trumpet,
Saying, I am Alpha and Omega, the first and the last: and, What thou seest, write in a book, and send it unto the seven churches which are in Asia; unto Ephesus, and unto Smyrna, and unto Pergamos, and unto Thyatira, and unto Sardis, and unto Philadelphia, and unto Laodicea.
And I turned to see the voice that spake with me. And being turned, I saw seven golden candlesticks; And in the midst of the seven candlesticks one like unto the Son of man, clothed with a garment down to the foot, and girt about the paps with a golden girdle....
And when I saw him, I fell at his feet as dead. And he laid his right hand upon me, saying unto me, Fear not; I am the first and the last:
I am he that liveth, and was dead; and, behold, I am alive for evermore, Amen; and have the keys of hell and of death." - Revelation 1:10-13, 17-18
Is their any doubt that the Alpha and Omega is the Lord Jesus Christ? (if so, cross-reference the description of this being with the one in Revelation 19:11-16)
2) Who is able to give him from the fountain of the water of life in Rev 21:6?
"Jesus answered and said unto her, Whosoever drinketh of this water shall thirst again:
But whosoever drinketh of the water that I shall give him shall never thirst; but the water that I shall give him shall be in him a well of water springing up into everlasting life." - John 4:13-14
Again, this points to Jesus.
3) Who shall be their God in vs 7?
The same person who is speaking as the Alpha and Omega and the giver of the water of life in vs 6: Jesus!
Let's see it all together again:
"And he said unto me, It is done. I am Alpha and Omega [Jesus], the beginning and the end. I will give unto him that is athirst of the fountain of the water of life freely [Jesus].
He that overcometh shall inherit all things; and I will be his God [Jesus], and he shall be my son." - Revelation 21:6-7 [inserts mine]
Seems pretty clear to me.
