Revelation 1:8-18
8I am Alpha and Omega, the beginning and the ending, saith the Lord, which is, and which was, and which is to come, the Almighty.
9I John, who also am your brother, and companion in tribulation, and in the kingdom and patience of Jesus Christ, was in the isle that is called Patmos, for the word of God, and for the testimony of Jesus Christ.
10I was in the Spirit on the Lord's day, and heard behind me a great voice, as of a trumpet,
11Saying, 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.
12And I turned to see the voice that spake with me. And being turned, I saw seven golden candlesticks;
13And 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.
14His head and his hairs were white like wool, as white as snow; and his eyes were as a flame of fire;
15And his feet like unto fine brass, as if they burned in a furnace; and his voice as the sound of many waters.
16And he had in his right hand seven stars: and out of his mouth went a sharp twoedged sword: and his countenance was as the sun shineth in his strength.
17And 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:
18I am he that liveth, and was dead; and, behold, I am alive for evermore, Amen; and have the keys of hell and of death.
The Young's Literal Translation Online Bible (YLT)
Isaiah 44:6 Thus said Jehovah, king of Israel, And his Redeemer, Jehovah of Hosts: `I [am] the first, and I the last, And besides Me there is no God.
MY COMMENT:If you look in Strong's you will see that the Tetragrammaton(God's name) was present when the King James version uses LORD. Note that the ASV, the YLT(posted above) and many others use Jehovah or Yahweh(God's name).
If your logic is that Rev 1:8-1:18 shows that Jesus is Jehovah(if not then what are you trying to show?), then that would mean that John had seen Jehovah. This would have the bible contradicting itself in more ways than one.
i.e. Isaiah 46 and
John 1:18
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 5:37
And the Father himself, which hath sent me, hath borne witness of me. Ye have neither heard his voice at any time, nor SEEN his shape.
John 6:46
Not that any man hath SEEN the Father, save he which is of God, he hath SEEN the Father.
MY COMMENT:You might want to look a little deeper. The trinity is the main argument used by unchristian religions to brand christiandom as false religion.
