God didn't answer Jesus prayer. A lot of times I like to think that God should always grant my prayer requests. I'm a good person, I only ask for good things, and I generally do the things God wants me to do. So why would he not answer my prayers.
It's just awesome to see that God doesn't answer Jesus prayer request. Jesus is begging God to not make Him go through with the crucifixion, but God tells Him that he must. And Jesus is way holier than I will ever be. JM
