What does the Bible say about repentance and remission?

The Bible clearly teaches that repentance and remission of sins are intricately connected with the gospel message. In Luke 24:47, we see the command to preach repentance and the forgiveness of sins in Christ’s name among all nations. This reflects the heart of the Christian message: Christ must needs have suffered, thus ensuring that repentance is not merely a change of mind, but a necessity born out of understanding who Christ is and what He accomplished on Calvary. Through Him, sins are not just made 'available' to be forgiven—they are, in fact, remitted entirely through His sacrifice. This means our sins are put away by the sacrifice of Christ, who bore the wrath of God on behalf of His people.
