" its beginnings prayer is so simple that the feeble child can pray, yet it is at the same time the highest and holiest work to which man can rise. It is fellowship with the Unseen and Most Holy One. The powers of the eternal world have been placed at its disposal. It is the very essence of true religion, the channel of all blessings, the secret of power and life. Not only for ourselves, but for others, for the Church, for the world, it is to prayer that God has given the right to take hold of Him and His strength. "

― Andrew Murray , Lord, Teach Us To Pray
