14. Thus, with this passage everything has been completely overthrown that has hitherto been preached about penance and satisfaction for sin, and all else that has been practiced and urged. For this reason there have been founded many orders and masses, and on this account we have become priests and monks and have run to and fro in order best in the world, which the world considers pious and holy, to get rid of sin. Therefore, it also follows: Whatever is that is nothing but mere sin and a damnable thing.
Thus we have considered one part of this Gospel.
15. The second thought then follows: “The Holy Spirit will convict the world in respect to righteousness, because I go to the Father,” says Christ, “and ye behold me no more.” Righteousness means piety and a good and honorable life before God. What is this now? It is, says Christ, “because I go to the Father.” We have often said about the resurrection of Christ that it came to pass not for his sake, but for our sakes, in order that we may apply it to ourselves as a blessing which is our own. For this reason he is risen from the dead and has ascended to heaven, that he might begin a spiritual kingdom, in which he reigns in us through righteousness and truth.
Therefore, he sits above; he does not rest and sleep, does not play with himself, but, as Paul says, Ephesians 1:22, has his work here upon the earth, governing the consciences and the souls of men with the Gospel.
16. Wherever Christ is now preached and acknowledged, there he reigns in us, from the right hand of his Father, and is himself here below in the hearts of men. There he reigns with might, power and dominion over you and all your enemies, and guards you from sin, death, devil and hell. Thus is his resurrection and ascension our comfort, life, blessing, righteousness and everything in one. This is what the Lord means when he speaks of righteousness, that the people thereby should become pious and righteous, that he ascends to heaven to the Father and we see him no more. This the world does not know, therefore the Holy Spirit must come and convict the world of it.
17. How does this come to pass? Just as we have heard. Am I to become pious, it will not be enough for me to perform outwardly good works, but I must do them from the bottom of my heart, gladly and willingly, so that I may be free from the fear of sin, death and the devil; be joyous, and with a good conscience, and all confidence stand before him and know how I stand with him. This no work, no creature can give unto me, but Christ alone, who has ascended into heaven — there, where one cannot see him, but must believe that he sits yonder and wishes to help one. Such a faith makes me acceptable unto God; Christ gives me the Holy Spirit into my heart, who makes me willing and happy in the doing of every good work. In this manner I become righteous, and in no other; for the works themselves make me more and more unwilling, the longer I occupy myself with them.
18. But the longer one is engaged in this work, the more willing it makes one’s heart; for wherever there is such knowledge, there the Holy Spirit cannot be wanting. When he comes, he makes the heart willing, joyful and happy, so that one may be free and willingly do what is pleasing to God, with joyous courage, and suffer whatever there is to suffer, yea, and even die willingly.
