The difference between unforgiveness and forgiveness depends on whose blood brings you peace. The blood of your enemy or the blood of your Savior.

If we refuse to forgive, we have stepped into dangerous waters. First, refusing to forgive is to put ourselves in the place of God, as though vengeance were our prerogative, not his. Second, unforgiveness says God’s wrath is insufficient. For the unbeliever, we are saying that an eternity in hell is not enough; they need our slap in the face or cold shoulder to “even the scales” of justice. For the believer, we are saying that Christ’s humiliation and death are not enough. In other words, we shake our fists at God and say, “Your standards may have been satisfied, but my standard is higher!” Finally, refusing to forgive is the highest form of arrogance. Here we stand forgiven. And as we bask in the forgiveness of a perfectly holy and righteous God, we turn to our brother and say, “My sins are forgivable, but yours are not.” In other words, we act as though the sins of others are too significant to forgive while simultaneously believing that ours are not significant enough to matter.
