17These people are as useless as dried-up springs or as mist blown away by the wind. They are doomed to blackest darkness.
18They brag about themselves with empty, foolish boasting. With an appeal to twisted sexual desires, they lure back into sin those who have barely escaped from a lifestyle of deception.
19They promise freedom, but they themselves are slaves of sin and corruption. For you are a slave to whatever controls you.
20And when people escape from the wickedness of the world by knowing our Lord and Savior Jesus Christ and then get tangled up and enslaved by sin again, they are worse off than before.
21It would be better if they had never known the way to righteousness than to know it and
then reject the command they were given to live a holy life.
22They prove the truth of this proverb: “A dog returns to its vomit.”
g And another says, “A washed pig returns to the mud.”
So I would assume you believe once a person repents and is baptized and obeys and lives a Holy life, if they return to sin "willfully" and will not repent -- God is still going to allow this unrepentant sinner in to His family? Nope!
I hope I have misunderstood and if I have please forgive me.
