Some great quotes from John Bunyan on prayer—
“Prayer is a sincere, sensible, affectionate pouring out of the soul to God, through Christ, in the strength and assistance of the Spirit, for such things as God has promised.”
“The best prayers have often more groans than words.”
“Prayer is a shield to the soul, a sacrifice to God, and a scourge for satan.”
“When you pray, rather let your heart be without words than your words without heart.”
Craig T. Owens
