In Romans 8:3-4, we have it scripturally detailed! I quote from Good News Translation: “What the Law could not do, because human nature was weak, God did. He condemned sin in human nature by sending his own Son, who came with a nature like our sinful nature, to do away with sin. God did this so that the righteous demands of the Law might be fully satisfied in us who live according to the Spirit, and not according to human nature.” That’s it!!!
