God created us to live with a single passion: to joyfully display his supreme excellence in all spheres of life. The wasted life is the life without this passion. God calls us to pray and think and dream and plan and work, not to be made much of, but to make much of him in every part of our lives.
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 PiperWill I find spiritual communion with God sweet enough, and hope in his promises deep enough, not just to cope, but to flourish and rejoice in him?
