Martin Luther Quote (The Preacher's Theme and the Christian's Preoccupation))

"...The great and important article of faith, called 'the forgiveness of sins'...is the one great and difficult art of a Christian, where he will have enough to learn as long as he lives, so that he need not look for anything new, higher or better. ...For this is, as has been said, the skill and the wisdom of the Christian, but it is so high and great that even all the beloved Apostles could not speak enough of it; and yet it meets the painful misfortune that no art is mastered as soon as this. There is no greater theme for a preacher than the grace of God and the forgiveness of sin, yet we are such wicked people, that, when we have once heard or read it, we think we know it, are immediately masters and doctors, keep looking for something greater, as though we had done everything , and thus we made new factions and divisions. I have now been teaching and studying this subject with all diligence for many years (more than any one of those who imagine they know it all), in preaching, writing, and reading, yet I cannot boast of having mastered it and am glad that I still remain a pupil with those who are just beginning to learn" (Luther The Righteousness of the World and of the Christian, and the Power on Earth to Forgive Sins Sermon Points 1, 12, 13).
