Another instance of Jesus being shown as Deity is Colossians 2:9
“For in Christ all the fullness of the Deity lives in bodily form”

Jesus Himself refers to being the Alpha & Omega
Rev 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.”
- Jehovah Witnesses will dispute that the above scripture is Jesus speaking. So we need to have them look at the previous verse:
Rev 1:7
7Look, he is coming with the clouds,
and every eye will see him,
even those who pierced him;
and all the peoples of the earth will mourn because of him. So shall it be! Amen.
- notice PIERCED HIM. That is what happened to Christ on the cross.
Then go to Revelation 22:12-13 where Jesus says He is coming soon:
12″Behold, I am coming soon! My reward is with me, and I will give to everyone according to what he has done. 13I am the Alpha and the Omega, the First and the Last, the Beginning and the End.
- and again refers to Himself ast the First and Last, Beginning and the End. Only Deity could be the First and Last, the Beginning and the End.
Next go to the Old Testament where Isaiah is speaking the Lord’s words:
6 “This is what the LORD says—
Israel’s King and Redeemer, the LORD Almighty:
I am the first and I am the last;
apart from me there is no God.
- Deity Himself is stating that He is the First and the Last. The same words used by Jesus in Rev 22:13.
And again in Isaiah 48:12-13
12 “Listen to me, O Jacob,
Israel, whom I have called:
I am he;
I am the first and I am the last.

13 My own hand laid the foundations of the earth,
and my right hand spread out the heavens;
when I summon them,
they all stand up together.

Then back to Revelation 22:!5 – where Jesus has been speaking the entire time.
16″I, Jesus, have sent my angel to give you[a] this testimony for the churches. I am the Root and the Offspring of David, and the bright Morning Star.”
Next look at Isaiah 44:6
This is what the LORD says—
Israel’s King and Redeemer, the LORD Almighty:
I am the first and I am the last;
apart from me there is no God.
— again God is the first and the last, just as Jesus claimed to be.
Finally, look at Revelation 22:20
20He who testifies to these things says, “Yes, I am coming soon.”
Amen. Come, Lord Jesus.
— so this shows that Jesus has been the One speaking in Revelation about Himself as Deity.
