The Alpha and Omega, The First and Last

Last Saturday, I heard a knock at the door.  Thinking it was one of my son's friends, I waited for him to open the door.  Another knock; no answer.  A third knock got me off my chair.  Peeking out the window, I saw a Jehovah's Witness approaching the neighbor's driveway.  I ran to the door.  By the time I opened it, the second Jehovah's Witness was half-way down my driveway.

"I'm home!" I yelled, hoping that he would come back.  

Hearing my call, he did an about face and returned to the door quoting a verse from Isaiah: "And no resident will say, 'I am sick;' the people who dwell there will be forgiven their iniquity."   "Do you believe that will ever happen?" he asked.  He seemed surprised when I told him that I thought the verse would be fulfilled.

Then I asked him if he thought that Jesus is God.  That question launched us into a discussion of several points including Revelation 22:13 "I am the Alpha and the Omega, the first and the last, the beginning and the end."  When I asked to whom that referred, he said it depends on the context.

Agreeing with him, I noted that the context indicates that Jesus is the one speaking.  Then I mentioned Revelation 1:8 "'I am the Alpha and the Omega,' says the Lord God, 'Who is and who was and who is to come, the Almighty.'"  In the New World Translation, the "Lord God" is translated "Jehovah."  How could there be two Alphas and two Omegas?  Jesus must be Jehovah.

Again, he said it depends upon the context, indicating that he had another appointment and had to leave.  However, he wanted to set up a time to meet again so we could explore the verse further.

I assume that he has heard this argument before, because he told me that he has been a Jehovah's Witness for 44 years. 

He is coming back in a couple of days with his Greek Interlinear.  What do you think he'll say?
