yet we have Christ as our advocate to make constant intercession for us as we grow as you say bit by bit, until we finalize this fact, are you forgiven by God 100% of the time, via the death of Christ at the cross?
Is God executing any more forgiveness after the cross. on anyone's behalf? Once they see this final death, sacrifice and last shedding of blood. then just maybe one might see the resurrected life God has for them here and now. where in God's Spirit there is no possibility for any more sin.
