He does not know how to discern the difference of one who lives in sin as a practice with no regard for grace or the righteousness of God and one who has isolated bouts with sin but has a heart after grace and the righteousness of God. He looks at the outward appearance and makes his determination on what he sees, while God looks at the heart and works on that heart accordingly. Someone who has heard and rejects the gospel and flaunts their sin should be told to repent of not only their attitude toward the gospel but also of their lifestyle of sin. We may win them through fear keeping them out of the fire (Jude 23).
So if a serial killer cuts back and only murders perhaps once or twice a year is that just an isolated bout? I would think that someone like that would still be a murderer at heart.
Same with a liar, thief, child molester or a rapist. You cannot indulge yourself occasionally and think you are right with God no way.
What you are saying might tickle your ears and the ears of others but it is clearly in direct contradiction with the Bible.
Paul doesn't use the words habitually when he says...
1Co 6:9 Know ye not that the unrighteous shall not inherit the kingdom of God? Be not deceived: neither fornicators, nor idolaters, nor adulterers, nor effeminate, nor abusers of themselves with mankind,
1Co 6:10 Nor thieves, nor covetous, nor drunkards, nor revilers, nor extortioners, shall inherit the kingdom of God.
He simply says that those people will not enter the kingdom and don't be deceived about it.
Gal 5:19 Now the works of the flesh are manifest, which are these; Adultery, fornication, uncleanness, lasciviousness,
Gal 5:20 Idolatry, witchcraft, hatred, variance, emulations, wrath, strife, seditions, heresies,
Gal 5:21 Envyings, murders, drunkenness, revellings, and such like: of the which I tell you before, as I have also told you in time past, that they which do such things shall not inherit the kingdom of God.
He again he gives a very specific lists of the works of the flesh and specifically says that those who do such things will not inherit the kingdom.
People explain it away or just ignore it. I saw in another post someone claim that these warnings were only to unbelievers. That is nonsense because the unbelievers are already doing those things.
God is calling people from darkness to light. Those in the light walk after the Spirit with their flesh in total submission. Those who are not willing to forsake their sin will deny this message.
It was ONE SIN that condemned Adam and Eve. They only ate a piece of fruit in disobedience to God.
It is not any different today.
A person is either walking in the Spirit or they are walking in the flesh. They cannot serve both and there is no grey area.
