What did you expect?? by Paul Tripp pg 235

Grace gives your marriage a lifetime warranty. What this means is that God will give you everything you need to be what you are supposed to be and do what he has called you to do in your marriage. But you must do it. His grace enables, reconciles, restores, and repairs. His grace teaches you and changes you. His grace gives you what you need to ask forgiveness and to forgive. His grace empowers you to overlook minor offenses and target what is truly important. His grace helps you see with greater and greater wisdom. His grace gives you strength to continue when you feel like quitting. His grace gives you strength to resist temptation and to turn and do what is right. His grace rescues you from your obsession with self-love and welcomes you to joyous wok of loving another. His grace enables you to be good and angry at the same time. When grace works a commitment of God's kingdom and righteousness in your heart, you will be angry at what sin does to you, to those you love, and to the situations in which you live, and that anger will motivate you to be a tool of change. His grace causes you to be committed to giving grace. His grace is a marriage warranty, because it gives you what you need, but what you get is grace in motion.
