1) God did not take pen in hand and write Sacred Scripture.  Humans did [inspired to write by God].  But the humans wrote from THEIR perspective.
2) Remember that the Gospels were written AFTER  Jesus' death and resurrection.  That is how humanity sees God's hand.  God never punishes to destroy, but to restore.  We have a choice to accept this or not
3) Do you see Jesus' soul as a separate entity from his body and life? [how could Jesus suffer if he saw the Beatific Vision?].
4) I stated that as the plot was thickening, Jesus could certainly perceive what the religious hierarchy was planning for him, and he certainly understood it perfectly in the Garden.  And yes, Jesus knew that this Cup of suffering would not pass from him.
5) God writes 'straight with all the crooked lines' that humanity uses.  On the Cross, the Trinity was present---Jesus, with faith and trust, offered his life and all that he did to the Father, and the Spirit infusing the Love/Forgiveness of God back to us.
