Forgiveness is the exclusive domain and the divinely given privilege of the redeemed.
Non-Christians cannot be free from sin because they are children of the devil, and God will not forgive any transgression until they become children of the light.
Believers, however, can experience release from all their transgressions through forgiveness.
This divinely granted gift is the means of grace that allows us to have relationships as God intended, bringing us to the all-important question: How do you live out forgiveness, practically speaking?
