1 Corinthians 6:11 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 by the Spirit of our God.
And thus are Christians. They are washed, sanctified, and justified and no longer identified by their sin, but by their position in Christ.
People are saved in the midst of their to begin with. Their sin is not going to keep them from getting saved and not going to keep them from staying saved.
So the claim that sin sends a Christian to hell is a false claim.
If someone is a Christian, they are not going to hell even if and when they sin.
A person who is going to hell is not and never has been a Christian.
No, those verses do not say that those who do those sins will not inherit the kingdom of God.
It says the unrighteous will not inherit the kingdom of God.
The unrighteous are those not saved, those who are not born again believers.
