Phil 2:5 You should have the same attitude toward one another that Christ Jesus had,
2:6  who though he existed in the form of God

Key texts include:

John 6:38 “I have come down from heaven not to do my own will but the will of the one who sent me.”

John 14:28 “You heard me say to you, ‘I am going away and I am coming back to you.’ If you loved me, you would be glad that I am going to the Father, because the Father is greater than I am.”

John 17:3 “Now this is eternal life—that they know you, the only true God, and Jesus Christ, whom you sent.”

The literature (especially online literature dating from 2016 onwards) is huge.

Here, however, is a selection.
