Maintaining joy in God takes 'work'; that is, it's a fight against every impulse for alien joys and every obstacle in the way to seeing and savoring Christ.
John PiperGod has given us prayer as a wartime walkie-talkie so that we can call headquarters for everything we need as the kingdom of Christ advances in the world. Prayer gives us the significance of front-line forces, and gives God the glory of a limitless Provider. The one who gives the power gets the glory. Thus prayer safeguards the supremacy of God in missions while linking us with endless grace for every need.
John PiperMarriage is not mainly about prospering economically; it is mainly about displaying the covenant-keepin g love between Christ and his church. Knowing Christ is more important than making a living. Treasuring Christ is more important than bearing children. Being united to Christ by faith is a greater source of marital success than perfect sex and double-income prosperity.
