Pslams 83:16-18 ; Isaiah 43:10 "YOU​ are my witnesses," is the utterance of Jehovah, "even my servant whom I have chosen, in order that ​YOU​ may know and have faith in me, and that ​YOU​ may understand that I am the same One. Before me there was no God formed, and after me there continued to be none.11 I—I am Jehovah, and besides me there is no savior."
12 "I myself have told forth and have saved and have caused [it] to be heard, when there was among ​YOU​ no strange [god]. So ​YOU​ are my witnesses," is the utterance of Jehovah, "and I am God.13 Also, all the time I am the same One; and there is no one effecting deliverance out of my own hand. I shall get active, and who can turn it back?
John 4:34. ; 1 Corinthians 15:23 But each one in his own rank: Christ the firstfruits, afterward those who belong to the Christ during his presence.24 Next, the end, when he hands over the kingdom to his God and Father, when he has brought to nothing all government and all authority and power.25 For he must rule as king until [God] has put all enemies under his feet.26 As the last enemy, death is to be brought to nothing.27 For [God] "subjected all things under his feet." But when he says that 'all things have been subjected,' it is evident that it is with the exception of the one who subjected all things to him.28 But when all things will have been subjected to him, then the Son himself will also subject himself to the One who subjected all things to him, that God may be all things to everyone.
