13:38-41 Let all that hear the gospel of Christ, know these two things: 1. That through this Man, who died and rose again, is preached unto you the forgiveness of sins. Your sins, though many and great, may be forgiven, and they may be so without any injury to God's honour. 2. It is by Christ only that those who believe in him, and none else, are justified from all things; from all the guilt and stain of sin, from which they could not be justified by the law of Moses. The great concern of convinced sinners is, to be justified, to be acquitted from all their guilt, and accepted as righteous in God's sight, for if any is left charged upon the sinner, he is undone. By Jesus Christ we obtain a complete justification; for by him a complete atonement was made for sin. We are justified, not only by him as our Judge but by him as the Lord our Righteousness. What the law could not do for us, in that it was weak, the gospel of Christ does. This is the most needful blessing, bringing in every other. The threatenings are warnings; what we are told will come upon impenitent sinners, is designed to awaken us to beware lest it come upon us. It ruins many, that they despise religion. Those that will not wonder and be saved, shall wonder and perish.
38-41. the forgiveness of sins—the first necessity of the sinner, and so the first experienced blessing of the Gospel.
