Prayer is our lifeline to God, a medium in which our faith is strengthened. The Bible shows several positions or postures used in prayer, including kneeling, bowing the head, or lying prostrate (all conveying degrees of submission and humility), but gives special attention to the posture of raising hands, symbolic of giving up or admitting vulnerability. David prayed with raised hands when he had come to the end of his tether, indicating that prayer is a time when we surrender unconditionally to God's power. Joshua's victory over the Amalekites was assured only after Moses in a posture of contrite submission with hands raised, assisted by Aaron and Hur. God honors the prayer of those who are contrite and tremble at His word, as symbolized by hands raised in submission.
