Forgiveness in and of itself is difficult. I like to hold my grudges. We like to hold our grudges. But thinking about the grudges we hold when thinking about what Christ did humbles us to the point of shame and leads us to forgive others and repent for our hardheartedness. Not only did we commit an infinite offense against the Almighty, but we committed an infinite offense against him and he still loved enough to die for our forgiveness. This is mind blowing, theology shattering, and uncompromisingly humbling. It breaks down thick walls of pride and long lasting grudges. The thought itself is one of the most impossible facts to comprehend of all time.
Perhaps it's time now to forgive as we have been forgiven. There's no offense we could have had against us that's worth more than what we have done against Christ and he died for us. For us. So let's die to ourselves and our pride and forgive those who have wronged us and, in so doing, glorify Christ through our actions.
