The trinity is one being.
John 5:22-23 (NWT 2013)
22 For the Father judges no one at all, but he has entrusted all the judging to the
Son, 23 so that all may honor the Son just as they honor the Father. Whoever
does not honor the Son does not honor the Father who sent him.
Jesus is the one doing all of the judging. The Father judges no one at all.
Matthew 16:27 (NWT 2013)
For the Son of man is to come in the glory of his Father with his angels, and then
he will repay each one according to his behavior.
Jesus is saying he will come in the glory of his Father, and he is saying “I will repay each one
according to his behaviour”.
Revelation 22:12 (NWT 2013)
“‘Look! I am coming quickly, and the reward I give is with me, to repay each one
according to his work.
Since Jesus is the one who repays each one according to his work, who is speaking here? According
to what we just read in John and Matthew; it is Jesus.
Revelation 22:20 (NWT 2013)
“The one who bears witness of these things says, ‘Yes, I am coming quickly.’”
“Amen! Come, Lord Jesus.”
So, it is definitely Jesus speaking when saying “I am coming quickly”
Revelation 22:12-13 (NWT 2013)
“‘Look! I am coming quickly, and the reward I give is with me, to repay each one
according to his work. 13 I am the Alʹpha and the O·meʹga, the first and the last,
the beginning and the end.
Jesus has just said that he is the Alpha and Omega, since he is the one speaking.
Revelation 21:6-7 (NWT 2013)
And he said to me: “They have come to pass! I am the Alʹpha and the O·meʹga,
the beginning and the end. To anyone thirsting I will give from the spring of the
water of life free. 7 Anyone conquering will inherit these things, and I will be his
God and he will be my son.
Jesus is literally claiming to be God. Only God can be Alpha and Omega. Also see Isaiah 44:6, and Revelation 1:8
