I can see how Jesus would call God " my God" while on earth because positionally he was made “lower than the angels” as a man.
Him who overcomes I will make a pillar in the temple of my God. Never again will he leave it. I will write on him the name of my God and the name of the city of my God, the new Jerusalem, which is coming down out of heaven from my God; and I will also write on him my new name. Even in the book of Revelation (after his death, resurrection, and ascension), when Jesus has all authority in Heaven and on Earth, seated at the right hand of God, he still says “my God.”
Is this because Jesus is talking as a man in heaven? But doesn’t it sound like he’s speaking as God here? I’m not getting this.
