Jehovah alone is the First and the Last.
Establish JW agreement that only Jehovah holds this title. Then show Revelation 22 where Jesus explicitly takes it upon himself. The self-identification 'I, Jesus' makes it impossible to argue this is the Father speaking.
Jesus takes upon himself the very title that Jehovah says belongs to him alone.
I'd have to look that up.
Most JWs have not closely examined Revelation 22. The text is clear: 'I, Jesus.' There is no ambiguity.
Jehovah gave Jesus all authority.
Authority delegation does not transfer divine identity titles.
Revelation 1:8 isn't Jesus speaking — that's Jehovah interrupting. The speaker shifts mid-passage. Jesus is described in 1:7, but 1:8 is the Father's own declaration of himself.
There is no marker in the text for a speaker shift. Verse 7 says "Look! He is coming with the clouds, and every eye will see him, and those who pierced him." Verse 8 continues without break: "I am the Alpha and the Omega, says Jehovah God, the one who is and who was and who is coming, the Almighty." Even granting that 1:8 might be ambiguous, removes the ambiguity entirely. There Jesus himself says "I am the Alpha and the Omega, the First and the Last, the Beginning and the End... I, Jesus, sent my angel." The same divine title that 1:8 claims for the speaker, 22:13 places explicitly in Jesus's mouth. If the JW reading of 1:8 forces Jesus and the Father to share an exclusive divine title, the conclusion is not that the speaker shifts — it is that Jesus and the Father share the divine identity.
Don't get tangled in debates about Revelation 1:8. Stay on Revelation 22:16 where Jesus self-identifies.
