Forgive us as we forgive others.
What does this mean?
We pray in this request that our Father in heaven would not take our sins into account, or refuse to answer our prayers because of them. We do not deserve the things for which we pray, nor have we earned them. Nevertheless, we ask that he would give us what we pray for because of his kindness [grace]. We sin a lot every day and deserve nothing but punishment. That is why we forgive those who sin against us without any hesitation, and stand ready to help them.
