The ultimate difference between God's wisdom and man's wisdom is how they relate to the glory of God's grace in Christ crucified. God's wisdom makes the glory of God's grace our supreme treasure. But man's wisdom delights in seeing himself as resourceful, self-sufficient, self determining, and not utterly dependent on God's free grace.
John PiperObedience does not consist in paying God back and thus turning grace into a trade. Obedience comes from trusting in God for more grace - future grace - and thus magnifying the infinite resources of God's love and power.
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.
