In The Garden

Then they came to a place which was named Gethsemane; and He said to His disciples, "Sit here while I pray."  And He took Peter, James, and John with Him, and He began to be troubled and deeply distressed.  Then He said to them, "My soul is exceedingly sorrowful, even to death. Stay here and watch."-Mark 14:32-34

Our Lord's struggle in the Garden can be understood only in the light of what would happen to Him on the cross: He would be made sin for us  and bear the curse of the Law . It was not the physical suffering that almost overwhelmed Him with "anguish and sorrow," but the contemplation of being forsaken by His Father . This was "the cup" that He would drink .
