Mark 14:35 Going a little farther, he fell to the ground and prayed that if possible the hour might pass from him.
Mark 15:23 They offered him wine mixed with myrrh, but he did not take it.
The New Scofield Study Bible footnote states: "Wine and myrrh mixed together composed a stupefying drink which was sometimes given to those who were in great pain in suffering such as must be endured in crucifixion."
When I want to avoid something, I'm more likely to pray the hour won't come at all. When I know I must do something uncomfortable, I pray that the hour will come and pass quickly.
This reminded me of my son's birth. The nurses were telling me mid-morning that it looked like he would be born before lunch. As the pain increased I chose to have an epidural (pain killer). My son was born after 7:30pm.In reading about Jesus refusing the pain killer, I wondered how often I pray for God to relieve my pain at the cost of extending my suffering. Yes, it is in suffering that we develop perseverance (Romans 5:3), but suffering itself is not the goal. Christ was wise enough not to ask for pain relief. He was willing to get it over with so that he could get to the purpose of the suffering.
The image of Christ I'm getting here is that he did not intend to wait for a more comfortable solution. Accomplishing God's work was a greater motivator than avoiding the pain.
