Forgiving one another, even as God for Christ's sake has forgiven you (Ephesians 4:32b) is a verse that we as saints of God must learn to do. God has forgiven us for all the wrong that we have done and saved us. Because of God's grace, all that come to Him in repentance will be forgiven. It's God desire that all come to repentance and be saved. You can be forgiven of all past sins because God loves us and made a way for us to be saved. By accepting His plan of Salvation which is accepting Jesus Christ as your Lord and Savior, old things are past away and now you are new in the Lord Jesus.
