[N]obody can produce new evidence of your depravity that will make God change his mind. For God justified you with (so to speak) his eyes open. He knew the worst about you at the time when he accepted you for Jesus' sake; and the verdict which he passed then was, and is, final.
J. I. PackerThe whole story of the Father's Christ-exalting plan of redeeming love, from eternity to eternity, must be told, or the radical reorientation of life for which the gospel calls will not be understood, and the required total shift from man-centeredness to God-centeredness, and more specifically from self-centeredness to Christ-centeredness, will not take place.
J. I. PackerWe need to discover all over again that worship is natural to the Christian, as it was to the godly Israelites who wrote the psalms, and that the habit of celebrating the greatness and graciousness of God yields an endless flow of thankfulness, joy, and zeal.
J. I. PackerIt has been said that in the New Testament doctrine is grace; and ethics is gratitude; and something is wrong with any form of Christianity in which, experimentally and practically, this saying is not being verified. Those who suppose that the doctrine of God's grace tends to encourage moral laxity are simply showing that, in the most literal sense, they do not know what they are talking about. For love awakens love in return; and love, once awakened, desires to give pleasure.
J. I. Packer
