Well, the plan to redeem man was from before creation. He said he had food to eat, and that was to do His Father's will. I took your one post to mean the Christ, whilst praying at Gethsamane, could have chosen to bail. If that wasn't your thought, please forgive me.
But, ppl take it that when Jesus mentioned 12 legion of angels, that He could have asked and the angels would have rescued Him. And if He would have, then the scriptures become broken, null and void, no longer trustworthy, &c.
