There are many passages in the NT that deal with forgiveness. The ones that I can think of deal with forgiving fellow believers who are in the body of Christ ("forgiving one another even as God for Christ's sake has forgiven you" comes to mind). But, what about unsaved people. What is the theological basis for a Christian to forgive an unsaved person. For instance, when a murder takes place and the victim is a Christian, we often see the family of the victim making statements of forgiveness toward the murderer. What is the theological rationale for this?
