Nothing is more vital than prayer in Christian existence, and few things are more vulnerable to neglect.
John PiperA Christian is not a person who believes in his head the teachings of the Bible. Satan believes in his head the teachings of the Bible! A Christian is a person who has died with Christ, whose stiff neck has been broken, whose brazen forehead has been shattered, whose stony heart has been crushed, whose pride has been slain, and whose life is now mastered by Jesus Christ.
John PiperThere is no other way the world is going to see the supreme glory of Christ today, except that we break free from the Disneyland of America and begin to live lifestyles of missionary sacrifice that looks to the world like our treasure is in heaven and not on the earth.
