I have been meditating on the forgiveness of God as being his breath-taking gift to all who put their trust in Jesus. Does that mean that when we forgive another we are offering them a precious gift? It certainly cost the Father dearly: the life of his one and only Son. And when we forgive another it can often be incredibly costly to us. 

I remember praying with a church leader who was literally sweating and in agony as he fought to get to the place where he could forgive his step-mother for stealing his father away from him when he was very young. She went on to undermine him to his father and tried to keep them apart. Jesus commanded us not to judge others, but to love them and to forgive them. When we refuse to do this we get "turned over to the jailers to be tortured" that is, we open the door for the evil one to torment us (Mt. 18:21-35). That had been happening to this leader, but he did forgive her and was set free.

Rather than freely forgiving others, our society gets absorbed in the blame-game; in demanding its "pound of flesh"; in refusing to be merciful and to cancel the "debt" owed and insisting on "imprisoning" the offender. But it is the one who refuses to forgive who gets locked up in the prison of their own making. 

For the Christian, freely forgiving others is not a gift we give but a command we obey (Mt. 6:12-15; Mk. 11:25; Col. 3:13). We do not forgive because the person is repentant and pleads with us to do so. We forgive because God has forgiven us, and we do this regardless of whether they are sorry or not.

I couldn't find an example in the Bible of someone laying the blame for something on someone else, whether justifiably or not. I found "I will bear the blame" a few times with the meaning "You can hold me responsible for the consequences" and a number of references to God wanting our walk with him to be "blameless", that is righteous and true, full of integrity and honouring of others, but not a statement like "I blame you for such and such". Believers have this wonderful promise: "He will keep you strong to the end, so that you will be blameless on the day of our Lord Jesus Christ.God who called you into fellowship with his Son, is faithful" (1 Cor. 1:8).
