Ephesians 4:32
"And be ye kind one to another, tenderhearted, forgiving one another, even as God for Christ's sake hath forgiven you."
And how has God forgiven us?
Colossians 2:13-14
"And you, being dead in your sins and the uncircumcision of your flesh, hath he quickened together with him, having forgiven you all trespasses;
Blotting out the handwriting of ordinances that was against us, which was contrary to us, and took it out of the way, nailing it to his cross"
