I know it is.The quotation is a direct quotation of Psalm 22 "My God, my God! Why have you forsaken me?"
Yes, but I am not God. I am seperate to him, just as Jesus was when he was human. And why would Jesus ask that question if he was God, knowing the answer.Since Jesus is also fully human, Jesus could speak to God (Father) in such a way, just as any of us are able to.
The same Goes for his praying. He prayed not to himself but to his God. And when he didn't he ask if the cup could be removed then let that happen, but let not his will take place but the will of the father? How could he, why would he, possibly ask for such a thing if he had the power to remove the cup anyway? I don't understand how you can read another meaning into such accounts.
