If that is so, why did Our Lord repeat the same prayer in the garden the night before His Passion and Death?
Where did you get that from? My sources say:
Luke 22:39-53
39 He came out and went, as was his custom, to the Mount of Olives; and the disciples followed him. 40When he reached the place, he said to them, ‘Pray that you may not come into the time of trial.’* 41Then he withdrew from them about a stone’s throw, knelt down, and prayed, 42‘Father, if you are willing, remove this cup from me; yet, not my will but yours be done.’ [[ 43Then an angel from heaven appeared to him and gave him strength. 44In his anguish he prayed more earnestly, and his sweat became like great drops of blood falling down on the ground.]]* 45When he got up from prayer, he came to the disciples and found them sleeping because of grief, 46and he said to them, ‘Why are you sleeping? Get up and pray that you may not come into the time of trial.’* 47 While he was still speaking, suddenly a crowd came, and the one called Judas, one of the twelve, was leading them. He approached Jesus to kiss him; 48but Jesus said to him, ‘Judas, is it with a kiss that you are betraying the Son of Man?’ 49When those who were around him saw what was coming, they asked, ‘Lord, should we strike with the sword?’ 50Then one of them struck the slave of the high priest and cut off his right ear. 51But Jesus said, ‘No more of this!’ And he touched his ear and healed him. 52Then Jesus said to the chief priests, the officers of the temple police, and the elders who had come for him, ‘Have you come out with swords and clubs as if I were a bandit? 53When I was with you day after day in the temple, you did not lay hands on me. But this is your hour, and the power of darkness!’
