I think this passage speaks volumes about Jesus attitude before the Father. Yes, Jesus did present His request to the Father, that ‘this cup’ be removed from Him, but throughout this time, Jesus wasn’t angry, annoyed, or frustrated. He was still in total and complete submission to the will of the Father. His agony in v44 I think models for us what true prayer looks like in times of crisis, when we are in situations of great distress. It’s not wrong to present our requests to God, yet ultimately our agony must be in submission to God – we must agonize to submit our will to Him, not to demand that He work on our terms.
