The thought of building a life around minimal morality or minimal significance—a life defined by the question, “What is permissible?”—felt almost disgusting to me. I didn’t want a minimal life. I didn’t want to live on the outskirts of reality. I wanted to understand the main thing about life and pursue it.
John PiperWhat is the essence of evil? It is forsaking a living fountain for broken cisterns. God gets derision and we get death. They are one: choosing sugarcoated misery we mock the lifegiving God. It was meant to be another way: God's glory exalted in our everlasting joy.
John PiperPeople are not prepared or able to rejoice in suffering unless they experience a massive biblical revolution of how they think and feel about the meaning of life. Human nature and American culture make it impossible to rejoice in suffering. This is a miracle in the human soul wrought by God through His Word.
John PiperThe assurance of the believer is not that God will save him even if he stops believing, but that God will keep him believing--God will sustain you in faith, he will make your hope firm and stable to the end. He will cause you to persevere.
