We can say that true gratitude does not give rise to the debtor's ethic because it gives rise to faith in future grace. With true gratitude there is such a delight in the worth of God's past grace, that we are driven on to experience more and more of it in the future...it is done by transforming gratitude into faith as it turns from contemplating the pleasures of past grace and starts contemplating the promises of the future.
John PiperA Christian is not a person who believes in his head the teachings of the Bible. Satan believes in his head the teachings of the Bible! A Christian is a person who has died with Christ, whose stiff neck has been broken, whose brazen forehead has been shattered, whose stony heart has been crushed, whose pride has been slain, and whose life is now mastered by Jesus Christ.
John PiperGrace is not simply leniency when we have sinned. Grace is the enabling gift of God not to sin. Grace is power, not just pardon.
John PiperLoving God with all our mind means that our thinking is wholly engaged to do all it can to awaken and express the heartfelt fullness of treasuring God above all things.
