Time for some old timer protestant bible scholars on 1 Cor 9:
Gill commentary on the bible:
Be not deceived imagining, that through your knowledge and profession you shall be saved, live as you will:
PNT:
Be not deceived. Let no one make the mistake of thinking that any unrighteous man shall be an heir.
Wesley:
1Co 6:9 Idolatry is here placed between fornication and adultery, because they generally accompanied it. Nor the effeminate - Who live in an easy, indolent way; taking up no cross, enduring no hardship. But how is this? These good - natured, harmless people are ranked with idolaters and sodomites! We may learn hence, that we are never secure from the greatest sins, till we guard against those which are thought the least; nor, indeed, till we think no sin is little, since every one is a step toward hell.
Henry:
1Co 6:9-11
The Corinthians are warned against many great evils, of which they had formerly been guilty. There is much force in these inquiries, when we consider that they were addressed to a people puffed up with a fancy of their being above others in wisdom and knowledge. All unrighteousness is sin; all reigning sin, nay, every actual sin, committed with design, and not repented of, shuts out of the kingdom of heaven. Be not deceived. Men are very much inclined to flatter themselves that they may live in sin, yet die in Christ, and go to heaven. But we cannot hope to sow to the flesh, and reap everlasting life. They are reminded what a change the gospel and grace of God had made in them. The blood of Christ, and the washing of regeneration, can take away all guilt. Our justification is owing to the suffering and merit of Christ; our sanctification to the working of the Holy Spirit; but both go together. All who are made righteous in the sight of God, are made holy by the grace of God.
The opinions of these bible scholars and knowledgable theologians is that these verses applied to the believer as much as the unbeliever. Of course these men believed in a doctrine of works these old time baptist and prestbyerian men of God . *roll eyes here*
