When we ask of the Lord coolly, and not fervently, we do as it were, stop His hand, and restrain Him from giving us the very blessing we "pretend" that we are seeking.
Charles SpurgeonIntercessory prayer is exceedingly prevalent. What wonders it has wrought! The Word of God teems with its marvelous deeds. Believer, thou hast a mighty engine in thy hand, use it well, use it constantly, use it with faith, and thou shalt surely be a benefactor to thy brethren.
Charles Spurgeon
