2 Corinthians 2:10-11 (NIV)
Anyone you forgive, I also forgive. And what I have forgiven—if there was anything to forgive—I have forgiven in the sight of Christ for your sake, in order that Satan might not outwit us. For we are not unaware of his schemes.
We pray, search our hearts Lord and reveal to us any person we may hold offense against. Teach us to be quick to forgive one another.
Colossians 3:13 (NIV)
Bear with each other and forgive one another if any of you has a grievance against someone. Forgive as the Lord forgave you.
