Matthew 16:39&42
[Jesus] prayed, "My Father, if it is possible, may this cup be taken from me. Yet not as I will, but as You will."
He prayed, "My Father, if it is not possible for this cup to be taken away unless I drink it, may Your will be done."
In the Garden of Gethsemane, Jesus reveals His humanity, in shrinking away from the whole purpose for his becoming a Man--to "drink that cup" of suffering and separation from His Father. We know that He had real, genuine, strong temptation to not succumb to the Father's will, by both this passage and also when He had spoken to Peter at the Last Supper:
(v.23) Jesus turned and said to Peter "Get behind me, Satan! You are a stumbling block to me; you do not have in mind the things of God, but the things of men.
Jesus had been telling his closest friends about how he would be killed and rise from the dead and Peter, in his loyalty, wanted to protect him: but Jesus replied very strongly, saying, in effect, I will not allow you to be an enabler, enabling me to not have to go through with this! It must have been a strong temptation, to allow Peter to fight on his behalf, as he really didn't want to have to go through with it. We see Jesus passionately fighting the enemy, and emerging victorious!
Jesus was always in tune with his Father, and had agreed to this course before they even created this world. This is why Jesus was born--to die. We are each born so we can live. He came to take our sin upon himself. He had to be human in order to qualify to carry our sin-infested nature upon himself on the Cross, and he had to be God to be the eternal Person who could pay our eternal debt in time. So Jesus "became sin, for us," each one of us.
Even so, come, Lord Jesus!
Even so, come, Lord Jesus!
