Christian growth is a different issue and has nothing to do with salvation.
No one is 'becoming' eternally saved, either they are, or aren't. 1Co 1:18 For the preaching of the cross is to them that perish foolishness; but unto us which are saved it is the power of God.
“Well, then if you are justified once before God, you are saved (Eph.4:30).
Christian growth is a different issue and has nothing to do with salvation.”
AGAIN - which I have said....ad nauseum.
