"Though in its beginning prayer is so simple that the feeblest child can pray, yet it is at the same time the highest and holiest work to which man can use. It is the fellowship with the Unseen and Most Holy One ... It is the very essence of true religion, the channel of all blessings the secret of power and life."
The Lord then added that, "the spirit of prayer is missing in My church because My people's heart are cold towards Me."
