What does God say thst He will do (how, in the OT, is salvation described)?All one needs for eternal life is to believe the Gospel and sealed.
God shall chastice us, remind us and as we walk closer to Him in spiritual walk. That for Rewards but in no way affectsalvation.
He will take remove our old heart, our old spirit, and give us a new heart and spirit.
He will put His Spirit in us.
AND?
He will cause us to obey His commands.
We are saved for good works that we will do them.
The problem I see with your idea here is it allows for a "dead useless faith", allows for a "mind set on the flesh" to produce life, for a "mind set on the Spirit" not to "produce hood works that accompany salvation".
