This is why I am so earnest in my plea to you to learn the true and correct definition of Christ on the basis of these words of Paul: “who gave Himself for our sins.” If He gave Himself into death for our sins, then undoubtedly He is not a tormentor. He is not One who will cast down the troubled, but One who will raise up the fallen and bring propitiation and consolation to the terrified. Otherwise Paul would be lying when he says “who gave Himself for our sins.” If I define Christ this way, I define Him correctly, grasp the authentic Christ, and truly make Him my own. I avoid all speculations about the Divine Majesty and take my stand in the humanity of Christ. There is no fear here; there is sheer sweetness, joy, and the like. This kindles a light that shows me the true knowledge of God, of myself, of all creatures, and of all the wickedness of the kingdom of the devil.
Luther, Commentary on Galatians 1:3
