What is preaching the Gospel?

Now what can we conclude? This, that this can, yes, must, be preached to all men. Preaching the Gospel is merely saying to all men: Sinners, rejoice! Christ has already blotted out your sins; Christ has already reconciled you with God; Christ has already earned God’s grace for you; Christ has already fulfilled the Law; Christ has already procured a righteousness for you which avails before God; Christ has already conquered death, hell, and the devil; Christ has already earned the necessary worthiness for your entrance into heaven; in short, Christ has already completed the work of our salvation! -- C.F.W. Walther
Receive it daily, treasure, thank and tell what God has done for us in His Son and through the Spirit.
