"They went to a place called Gethsemane, and Jesus said to his disciples, 'Sit here while I pray.' He took Peter, James and John along with him, and he began to be deeply distressed and troubled. 'My soul is overwhelmed with sorrow to the point of death,' he said to them. 'Stay here and keep watch.'" NIV translation
Gethsemane is an olive garden on the lower part of the Mount of Olives. We are reminded of the fact that olive trees are a symbol of spiritual richness and it is here where Jesus went to pray. We notice that all of the disciples (except for Judas) went to the garden with Him but He chose His closest three to go a little further with Him.
Those three would see the anguish that was gripping Jesus. Why was Jesus troubled? He knew that he was going to die and be raised again so it could not be that. The fact was that He was going to face the greatest of the great rejections while He was on the cross. During the time that He was on the cross burdened with our sins, He would be rejected by His Father. God would have to turn His back on Jesus as He could not look on sin. This period of separation would have been the first of its kind for our Lord and that was what was troubling Him. As followers of Jesus Christ, we must ask ourselves if we feel the same anguish at the thought of not walking with Him even for an instant.
"Going a little farther, he fell to the ground and prayed that if possible the hour might pass from him. 'Abba, Father,' he said, 'everything is possible for you. Take this cup from me. Yet not what I will, but what you will.'" NIV translation
The cup that Jesus referred to is the wrath of God and, for Him, the worst part of the wrath was the separation from His Father. The wrath was both physical and spiritual death. The physical death did not bother Jesus but the idea of being spiritually separated from the Father was crushing to His soul. Nevertheless, He was willing to endure that for our sake.
