Satan's aim is to destroy our joy and trust and delight in God, and to make God look worthless in the world's eyes. Everytime someone forsakes God for the world, gets angry at God when part of the world is taken away from them, they highlight the world as valuable... and everytime someone stays with God, when the world is taken away, and praises God, they highlight the value and glory of God.
John PiperThere 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 PiperThe greatest stumbling block for children in worship is that their parents do not cherish the hour. Children can feel the difference between duty and delight. Therefore, the first and most important job of a parent is to fall in love with the worship of God. You can't impart what you don't possess.
John PiperWhy don't people ask us about our hope? The answer is probably that we look as if we hope in the same things they do. Our lives don't look like they are on the Calvary road, stripped down for sacrificial love, serving others with the sweet assurance that we don't need to be rewarded in this life.
John PiperThe vast majority of abortions are performed between the seventh and tenth week when the baby is already sucking his thumb, recoiling from pricking, responding to sound. All his organs are present, the brain is functioning, the heart is pumping, the liver is making blood cells, the kidneys are cleaning fluids, and there is a fingerprint. His genetic code is uniquely and unquestionably human. And, if we are willing, he can be seen by ultrasound.
John PiperSo saving grace, converting grace, for Augustine, is God's giving us a sovereign joy in God that triumphs over all other joys and therefore sways the will. The will is free to move toward whatever it delights in most fully, but it is not within the power of our will to determine what that sovereign joy will be.
John Piper
