We confess that our God is a just God, who punishes those who despise Him; but even more, does He stand ready to forgive those who trust in Him.
Forgiving others is a hard thing to do, especially when we have been greatly hurt by the sins others have committed against us. And yet, God does not hold our sins against us. Instead, He freely forgives us for the sake of Christ.
Micah knew that the Lord does not retain His anger forever, but will again have compassion on His people. From him we learn that the Lord will, indeed, have compassion on His people on the Final Day, even as He pardons and forgives us now in Christ.
