Many people are being misled by some misguided preachers who teach that once one has received the righteousness of God, the person can live their life in whatever way they want because grace is covering them. Hence you see acclaimed believers living in filth and more ungodly than the people they call unbelievers. Nowadays when someone says "I am born again", the hearer becomes wary instantly because many believers have been led that you can commit all manner of sins with impunity since you have 'righteousness of Christ'.
The Bible makes it clear that God is holy and nothing filthy can connect God. You are saved by grace so that you will live no longer for yourself but for Christ. You are no longer under the law of flesh but of the Spirit. (Read Romans chapter 6 well before arguing).
Now know this:
1 John 3:4-9 Everyone who makes a practice of sinning also practices lawlessness; sin is lawlessness. You know that he appeared to take away sins, and in him there is no sin. No one who abides in him keeps on sinning; no one who keeps on sinning has either seen him or known him. Little children, let no one deceive you. Whoever practices righteousness is righteous, as he is righteous. Whoever makes a practice of sinning is of the devil for the devil has been sinning from the beginning. The reason the Son of God appeared was to destroy the works of the devil.

Galatians 5:16-18
But I say, walk by the Spirit, and you will not gratify the desires of the flesh. For the desires of the flesh are against the Spirit, and the desires of the Spirit are against the flesh, for these are opposed to each other, to keep you from doing the things you want to do. But if you are led by the Spirit, you are not under the law.
Romans 6:1-2
What shall we say then? Are we to continue in sin that grace may abound? By no means! How can we who died to sin still live in it?
Galatians 5:19-21
Now the works of the flesh are evident: sexual immorality, impurity, sensuality, idolatry, sorcery, enmity, strife, jealousy, fits of anger, rivalries, dissensions, divisions, envy, drunkenness, orgies, and things like these. I warn you, as I warned you before, that those who do such things will not inherit the kingdom of God.

Now don't let any 'feel good' preacher trap you in their Antichrist teachings. Peace!
