May you ever cherish and treasure this thought. Christ is made a servant of sin, yea, a bearer of sin, and the lowliest and most despised person. He destroys all sin by Himself and says: “I came not to be served but to serve” (Matt. 20:28). There is no greater bondage than that of sin; and there is no greater service than that displayed by the Son of God, who becomes the servant of all, no matter how poor, wretched, or despised they may be, and bears their sins. It would be spectacular and amazing, prompting all the world to open ears and eyes, mouth and nose in uncomprehending wonderment, if some king’s son were to appear in a beggar’s home to nurse him in his illness, wash off his filth, and do everything else the beggar would have to do. Would this not be profound humility? Any spectator or any beneficiary of this honor would feel impelled to admit that he had seen or experienced something unusual and extraordinary, something magnificent. But what is a king or an emperor compared with the Son of God? Furthermore, what is a beggar’s filth or stench compared with the filth of sin which is ours by nature, stinking a hundred thousand times worse and looking infinitely more repulsive to God than any foul matter found in a hospital? And yet the love of the Son of God for us is of such magnitude that the greater the filth and stench of our sins, the more He befriends us, the more He cleanses us, relieving us of all our misery and of the burden of all our sins and placing them upon His own back. All the holiness of the monks stinks in comparison with this service of Christ, the fact that the beloved Lamb, the great Man, yes, the Son of the Exalted Majesty, descends from heaven to serve me.

Such benefactions of God might well provoke us to love and to laud God and to celebrate this service in song and sermon and speech. It should also induce us to die willingly and to remain cheerful in all suffering. For how amazing it is that the Son of God becomes my servant, that He humbles Himself so, that He cumbers Himself with my misery and sin, yes, with the sin and the death of the entire world! He says to me: “You are no longer a sinner, but I am. I am your substitute. You have not sinned, but I have. The entire world is in sin. However, you are not in sin; but I am. All your sins are to rest on Me and not on you.” No one can comprehend this. In yonder life our eyes will feast forever on this love of God. And who would not gladly die for Christ’s sake? The Son of Man performs the basest and filthiest work. He does not don some beggars torn garment or old trousers, nor does He wash us as a mother washes a child; but He bears our sin, death, and hell, our misery of body and soul. Whenever the devil declares: “You are a sinner!” Christ interposes: “I will reverse the order; I will be a sinner, and you are to go scotfree.” Who can thank our God enough for this mercy?
