A verse to remind these Free Grace people is 1 Co 6:9
9 Do you not know that the unrighteous will not inherit the kingdom of God? Do not be deceived; neither the immoral, nor idolaters, nor adulterers, nor sexual perverts, 10 nor thieves, nor the greedy, nor drunkards, nor revilers, nor robbers will inherit the kingdom of God. 11 And such were some of you. But you were washed, you were sanctified, you were justified in the name of the Lord Jesus Christ and in the Spirit of our God.
I get so tired of seeing this scripture get twisted constantly.
You missed that keyword "unrighteous". Those lifestyles are said to be engaged in continually by those who are not saved, because these people are of the world and have not been convicted of their sins.
V11 concludes it: "And such were some of you. But you (believers) were washed, but you were sanctified, but you were justified in the name of the Lord Jesus and by the Spirit of our God"
The distinction is made there. V11 addresses believers who have been made alive in Christ, who are no longer of the world. We're not sinless, but the point is that we don't have the same appetites that we did before we were saved. We've become new creatures in Christ.
Paul was writing to believers. Do you think any of his readers thought that unbelieving drunkards would inherit the kingdom of God. I do not think so. What they might be confused about was thinking that because they believed in Christ that they could commit these sins and still go to heaven. Paul was disabusing them of this notion.
The earlier part of the chapter is speaking of handling issues, and not going to the lost to sue the brethren.
The lost are of the world and not qualified to judge the redeemed. Believers will judge even angels, so how can they not resolve small matters amongst themselves. The Corinthians were acting no different from the lost, in that they were dragging each other before unbelievers to settle their differences over temporal things. Paul goes on to say
"do you not know that the unrighteous (non believers) will not inherit the Kingdom?" This is a rhetorical question and makes a point to them since brother was suing brother before unbelievers. Not very Christ like, and not a good witness to the lost either.
Much can be gleaned from V9-10.
As I said, that word "unrighteous" is referring to the lost/non believers, who are spiritually dead. Confirmation is then given of the lifestyle sins continually engaged in by them, since they've not been convicted of their sins.
It says "do not be deceived.... practicing homosexuals are unrighteous/lost/shall not inherit... practicing thieves are unrighteous/lost/shall not inherit" etc. How many today live these lifestyles while professing to be a christian?... yet evidently they are not truly saved. And how many of them will one day pick up their bible and the HS will use that scripture to convict them!!
V11 confirms that believers, having become new creatures in Christ, no longer engage in continual sinful lifestyles like the lost world. As the verse says "such were some of you" (before you were saved, some of you used to be thieves and homosexuals, etc, but no longer). But as I said in my other post, we have different desires and appetites, but we're not sinless, and will often face temptations and end up sinning.
