Through Jesus Christ's death and resurrection, our uncountable sins have been forgiven. We no longer have to pay the penalty that we owed for our transgressions. And now, because we have been forgiven much, we can also forgive our brothers and sisters of whatever offenses we have against them, knowing that we didn't deserve our forgiveness either.
"And such were some of you. But you were washed, you were sanctified, you were justified in the name of the Lord Jesus Christ and by the Spirit of our God." 1 Corinthians 6:11
