A 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 PiperBut whatever you do, find the God-centered, Christ-exalting, Bible-saturated passion of your life, and find your way to say it and live for it and die for it. And you will make a difference that lasts. You will not waste your life.
John PiperIgnatius, when he heard the clock strike, would say, "Now I have another hour to answer for." (Eph. 5:16)
John PiperWhere the Bible is esteemed as the inspired and inerrant Word of God, preaching can flourish. But where the Bible is treated merely as a record of valuable religious insight, preaching dies.
