There is a warning. The path of God-exalting joy will cost you your life. Jesus said, โWhoever loses his life for my sake and the gospelโs will save it.โ In other words, it is better to lose your life than to waste it. If you live gladly to make others glad in God, your life will be hard, your risks will be high, and your joy will be full. This is not a book about how to avoid a wounded life, but how to avoid a wasted life. Some of you will die in the service of Christ. That will not be a tragedy. Treasuring life above Christ is a tragedy.
John PiperWhen you are deeply peaceful and confident that, because of Christ, God will bring you safely to his eternal kingdom and be the all-satisfying Treasure of your life forever, then you are free to see the truth, and love the truth, and speak the truth no matter what, and joyfully spread a passion for the truth whose name is Jesus.
John PiperBad theology dishonors God and hurts people. Churches that sever the root of truth may flourish for a season, but they will wither eventually or turn into something besides a Christian church.
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 Piper
