Like all good things, prayer requires some discipline. Yet I believe that life with God should seem more like friendship than duty. Prayer includes moments of ecstasy and also dullness, mindless distraction and acute concentration, flashes of joy and bouts of irritation. In other words, prayer has features in common with all relationships that matter.
Philip YanceyAs the books of Job, Jeremiah, and Habakkuk clearly show, God has a high threshold of tolerance for what appropriate to say in a prayer. God can "handle" my unsuppressed rage. I may well find that my vindictive feelings need God's correction - but only by taking those feelings to God will I have the opportunity for correction and healing.
Philip YanceyRepentance, not proper behavior or even holiness, is the doorway to grace. And the opposite of sin is grace, not virtue.
