29. The parable stands in bold relief, and pictures us perfectly, what we are and can do with our boasted reason and free will. If the poor wounded man had desired to help himself, it would only have been worse for him, he would only have done harm to himself and irritated his wounds, and only prepared more misery and distress for himself.
Had he remained lying quiet, he would have had as much suffering. Thus it is when we are left to ourselves. We are always lost, we may lay hold where we will. Hitherto man has always acted thus, he has thought out many ways and methods how we might reform our lives and get to heaven.
One found this way, another that, therefore so many kinds of orders arose: in like manner the letters of indulgence and crusades originated; but they have only made evil worse. Such is the world, and it is thus finely portrayed in this wounded man, it lies in sins over head and ears and cannot help itself.
30. But the Samaritan who has fulfilled the law and is perfectly healthy and sound, comes and does more than both priest and Levite. He binds up the sores of the wounded man, pours in oil and wine, lifts him upon his own beast, and brings him into the inn, takes good care of him, and when he departs he carefully commends him to the host, and besides leaves him a sufficient supply of money, while neither the priest nor Levite would do one of these kind acts. The priest signifies the dear sainted fathers before Moses; the Levite the priesthood of the Old Testament. All these however have accomplished nothing by their works, and have passed by on the other side like this priest and Levite.
31. Therefore, if I had for example all the good works of Noah, Abraham and of all the dear fathers, they would still be of no benefit to me. They have indeed beheld the wounded man lying helpless and half dead, but they could not help it. He who lay there half dead, saw it too, but what of it, he could make it no better. The dear sainted fathers saw very well that the people lay in their sins over their ears, and also felt the anguish of sin, but what could they do to remedy it? They could make it only worse, but not better. These were the preachers of the law, and showed what the world was, namely, full of deadly sins, and it lay there half dead, and could not help itself, notwithstanding all its powers, reason and free will. Go then, thou beautifully painted rogue, and boast of thy free will, of thy merits and holiness!
32. But Christ, the true Samaritan, takes the poor man to himself as his own, goes to him and does not require the helpless one to come to him; for here is no merit, but pure grace and mercy; and he binds up his wounds, cares for him and pours in oil and wine, this is the whole Gospel from beginning to end. He pours in oil when grace is preached, as when one says: Behold thou poor man, here is your unbelief, here is your condemnation, here you are wounded and sore. Wait! All this I will cure with the Gospel. Behold, here cling firmly to this Samaritan, to Christ the Savior, he will help you, and nothing else in heaven or on earth will. You know very well that oil softens, thus also the sweet, loving preaching of the Gospel gives me a soft, mild heart toward God and my neighbor, so that I risk my bodily life for the sake of Christ my Lord and his Gospel, if God and necessity require it.
33. But wine is sharp and signifies the holy cross that immediately follows. A Christian need not look for his cross, it is always on his back. For he thinks as St. Paul says, 2 Timothy 3:12: “All that would live godly in Christ Jesus shall suffer persecution.” This is the court-color in this kingdom. Whoever is ashamed of the color, does not belong to this king.
