What does the Bible say about unforgiveness?"

The Bible has quite a bit to say about forgiveness and unforgiveness. Perhaps the most well-known teaching on unforgiveness is Jesus’ parable of the unmerciful servant, recorded in Matthew 18:21-35. In the parable, a king forgives an enormously large debt (basically one that could never be repaid) of one of his servants. Later, however, that same servant refuses to forgive the small debt of another man. The king hears about this and rescinds his prior forgiveness. Jesus concludes by saying, “This is how my heavenly Father will treat each of you unless you forgive your brother or sister from your heart” (Matthew 18:35). Other passages tell us that we will be forgiven as we forgive (see Matthew 6:14; 7:2; and Luke 6:37, for example).

Do not be confused here; God’s forgiveness is not based on our works. Forgiveness and salvation are founded completely in the person of God and by Jesus’ redeeming work on the cross. However, our actions demonstrate our faith and the extent to which we understand God’s grace (see James 2:14-26 and Luke 7:47). We are completely unworthy, yet Jesus chose to pay the price for our sins and to give us forgiveness (Romans 5:8. When we truly grasp the greatness of God’s gift to us, we will pass the gift along. We have been given grace and should give grace to others in return. In the parable, we are appalled at the servant who would not forgive a minor debt after having been forgiven his unpayable debt. Yet, when we are unforgiving, we act just as the servant in the parable.

Unforgiveness also robs us of the full life God intends for us. Rather than promote justice, our unforgiveness festers into bitterness. Hebrews 12:14-15 warns, “Make every effort to live in peace with everyone and to be holy; without holiness no one will see the Lord. See to it that no one falls short of the grace of God and that no bitter root rises up to cause trouble and defile many.” Similarly, 2 Corinthians 2:5-11 warns that unforgiveness can be an opening for Satan to derail us.

We also know that those who have sinned against us – whom we may not want to forgive – are held accountable by God (see Romans 12:19 and Hebrews 10:30). It is important to recognize that to forgive is not to downplay a wrongdoing or necessarily to reconcile. When we choose to forgive, we release a person from his indebtedness to us. We relinquish the right to seek personal revenge. We choose to say we will not hold his wrongdoing against him. However, we do not necessarily allow that person back into our trust or even fully release that person from the consequences of his sin. We are told that “the wages of sin is death” (Romans 6:23). While God’s forgiveness relieves us from eternal death, it does not always release us from the death-like consequences of sin (such as a broken relationship or the penalty provided by the justice system). Forgiveness does not mean we act as if no wrong has been done; it does mean we recognize that grace abundant has been given to us and that we have no right to hold someone else’s wrongdoing over his head.
