PRAY IN SUBORDINATION TO GOD'S WILL
Luke 22:42 "Father, if you are willing, take this cup from me; yet not my will, but yours be done."
If our prayers are not in subordination to God, then we are being insubordinate. Even Jesus struggled between doing his own will and that of his Father. He furthermore said, "I have come down from heaven not to do my will but to do the will of him who sent me." John 6:38
"During the days of Jesus’ life on earth, he offered up prayers and petitions with loud cries and tears to the one who could save him from death, and he was heard because of his reverent submission. Although he was a son, he learned obedience from what he suffered." Heb 5:7,8 Prior to his incarnation in human flesh, Jesus never experienced the struggle we have in obeying God. And thus from the things he suffered, he learned the experience of obedience.
Obedience is never really experienced until the one you are in subordination to commands you to do something you don't want.
Consider under what circumstance (perhaps even now) in which you may have to pray as Jesus did, "Not my will, but yours be done."
