He was praying. I believe He even said, "Father, if it is possible, take this Cup from Me." He was fully human and fully divine. The fully human part of Him made Him scared to die. Plus, He loved the world so completely, and He knew everything, so He knew that there were those who did not love Him back, and it really, really hurt. The Agony was so intense in the Garden that He began to sweat drops of blood. Believe it or not, this is possible. I have had that happen to me, as incredulous as it might sound. And it dealt with loving someone so completely and being in agony over the fact that that person did not feel the same way. Think of how much of a bigger scale that was for Jesus. He loved us so much, He lay down His life for us. And, yet, He knew, that the gift would not be appreciated by some.
