I would definitely say the condemnation will be harsh. I don't know why you call it discipline when Paul doesn't. There is no where you will ever find a believer being condemned, so I'm not sure why you would try and say such things.
Nathan. You are trying to convince us, using 1 Tim 3:6, that a recent convert who becomes puffed up in his leadership role........will be condemned the SAME as the devil. I am NOT.
If A believer in this position falls into that trap they may be condemned in their flesh BY the devil......1 Tim 3:6. The Lord may hand us over to the accuser to kill us physically. 1 Cor 5:5.
It is divine discipline in our flesh, because a believer/saved person cannot be condemned eternally. We are sealed with the Spirit the moment we believe. Hence the words ' recent convert' in 1 Tim 3:6. they are sealed with the Spirit the moment they believed and cannot be eternally condemned. Rom 8:1 NASB, Eph 4:30.
So the sealed, 'recent convert' in 1 Tim 3:6 cannot be condemned the SAME as the devil. But that believers flesh can be destroyed by the devil, so God can take the believer home. 1 Cor 5:5.
