Link to Cantate Sermon 2 - Fourth Sunday after Easter
The Lord addresses his disciples thus: “When the Comforter is come, he will convict the world in respect of sin, and of righteousness, and of judgment; of sin, because they believe not on me.”
2. Here we must let that be “sin” which is ascribed to, and included in, sin by the high majesty of heaven. In the text only unbelief is mentioned as sin, “because,” says the Lord, “they believe not on me.”
3. But what is it to believe on Christ? It is not simply to believe that he is God, or that he reigns in heaven in equal power with God the Father; many others believe that: But I believe on Christ when I believe that he is a gracious God to me and has taken my sins upon himself and reconciled me with God the Father, that my sins are his and his righteousness mine, that there is an intermingling and an exchange, that Christ is a mediator between me and the Father. For the sins of the whole world were laid upon Christ, and the righteousness of the Father, that is in Christ, will swallow up all our sins.
No sins dare and can remain upon Christ. Such faith makes me pure and acceptable to the Father. Of this faith the pope and our highly educated leaders know nothing to speak, much less to believe. They teach that man should do many good works if he is to be acceptable to God and be free from sin, and that then God imparts to him his grace.
4. However, here the Lord speaks quite differently, and says: “The Holy Spirit will convict the world in respect of sin, because they believe not on me.” Unbelief only is mentioned here as sin, and faith is praised as suppressing and extinguishing the other sins, even the sins in the saints.
Faith is so strong and overpowering that no sin dare put it under any obligation. Although sins are present in pious and believing persons, they are not imputed to them, nor shall their sins condemn them. This is Paul’s meaning when he says in Romans 8:1: “There is therefore now no condemnation to them that are in Christ Jesus, who walk not after the flesh, but after the Spirit.” Their hearts are cleansed by faith, as Peter writes in Acts 15:9. Therefore, whatever they do in this faith, in this assurance is all good, pure and pleasing to God. On the contrary, without this faith all their doings are sin and destruction, though their good works may shine and glitter as beautifully as they will, and ever though they raise the dead. For Paul says: “Whatsoever is not of faith is sin,” Romans 14:23.
