Bear with each other and forgive one another if any of you has a grievance against someone. Forgive as the Lord forgave you.
"Forgive as the Lord forgave you" is enough to to spend a lifetime considering. It has wrapped up in it not only your entire past (and also your present and future?) but also the mystery of gospel itself.
How much we are willing to forgive shows how much we believe we have been forgiven.
Therefore I tell you, because her many sins have been forgiven, she has loved much. But he who has been forgiven little loves little.
This is also practical. We all have people who we have grievances against, people who have hurt us or people who just annoy and bother us. The clear way to apply this truth is to forgive them, to seek reconciliation, to be patient, to love.
This is difficult to do, perhaps impossible with mere human determination. These verses claim that it is possible, however, and that in order to achieve it, it is necessary for us to understand our own failures and how deeply and perfectly God has forgiven them in Christ.
