More on prayer--this time from Sadhu Sundar Singh, (1889-1929), an Indian Christian missionary. You can download a free pdf book by Mr. Singh, At The Master's Feet, here.
"The essence of prayer does not consist in asking God for something but in opening our hearts to God, in speaking with Him, and living with Him in perpetual communion. Prayer is continual abandonment to God. Prayer does not mean asking God for all kinds of things we want; it is rather the desire for God Himself, the only Giver of Life. Prayer is not asking, but union with God. Prayer is not a painful effort to gain from God help in the varying needs of our lives. Prayer is the desire to possess God Himself, the Source of all life. The true spirit of prayer does not consist in asking for blessings, but in receiving Him who is the giver of all blessings, and in living a life of fellowship with Him."
