Don't confuse forgiveness with the acceptance of wrongdoing. If forgiveness had to do with the acceptance of a wrong then we would be saying God is accepting of our sin. Psalm 5 denies God's acceptance of sin, "You are not a god who delights in evil; no wicked person finds refuge with you." God wants always to be the source of our refuge. Thus, God did not send his Son into the world to condemn the world, but that the world might be saved through him (John 3:17). This is affirmed when St. Joseph was told by an angel, "You are to name him Jesus, because he will save his people from their sins” (Matthew 1:21). The power of forgiveness is transformative! Jesus' sacrifice on the cross opened the door of salvation and showed us the power of forgiveness. As we await the day of salvation with hope, it is now that Jesus invites us to share in the transformative nature of forgiveness by seeking often the forgiveness of God and by offering forgiveness to one another.
One last point! Before we get too comfortable and choose not to forgive one another. We may want to remember the words of Jesus, “If you forgive men their transgressions, your heavenly Father will forgive you. But if you do not forgive men, neither will your Father forgive your transgressions.”
