This document discusses the power of prayer through examining key Bible passages. It addresses where we should pray (alone in private), how we should pray (sincerely rather than for show), and whether we should pray since God knows our needs already. Jesus tells parables of a friend asking at midnight and a persistent widow to show we should keep asking God in prayer and not lose heart. We should spend quality time praying to develop our relationship with God, even though he knows our needs, and be persistent in prayer as God will answer in his time.
