Mark 14:39 Once more he went away and prayed the same thing.
When Jesus knew His time had come, He spent the hours before that praying to His Father in heaven; not just once, but time after time.
Each of us may change because we are all different, but God continues to be the same.
When we come to Him in prayer, we should not expect Him to be different each time; He does not change.
When we ask God for things in prayer, we should remain constant in our prayers so God knows we are serious about our prayers.
