Rev 1:17-18: Jesus says "I am the First and the Last... I was dead, and now I am alive."
In Isaiah 44:6 YHWH says "I am the first and I am the last; apart from me there is no God."
Either Jesus claims a title YHWH says no one shares, or Isaiah is wrong.
John falls at his feet and isn't rebuked (contrast 19:10). How does a mere man, or a lesser "lord," claim YHWH's exclusive title and accept that response?
