I think I am on to something with you, you deprecate the new birth being born of God as basically worthless regarding eternal salvation, and put the entire burden on man to stay in a 'correct relationship' with God.
I see constant messages in the Bible urging children of God who are saved of the consequences of turning back to their sinful nature. I see verses that include everyone , both believers and unbelievers that will not inherit the kingdom of God who live sinful lifestyles. I see verses saying that salvation is contingent upon standing firm and steadfast in the faith of the gospel. Here’s a few examples of scriptures that include everyone.
I am the true grapevine, and my Father is the gardener. He cuts off every branch of mine that doesn’t produce fruit, and he prunes the branches that do bear fruit so they will produce even more. You have already been pruned and purified by the message I have given you. Remain in me, and I will remain in you. For a branch cannot produce fruit if it is severed from the vine, and you cannot be fruitful unless you remain in me. “Yes, I am the vine; you are the branches. Those who remain in me, and I in them, will produce much fruit. For apart from me you can do nothing. Anyone who does not remain in me is thrown away like a useless branch and withers. Such branches are gathered into a pile to be burned.
John 15:1-6
When you follow the desires of your sinful nature, the results are very clear: sexual immorality, impurity, lustful pleasures, idolatry, sorcery, hostility, quarreling, jealousy, outbursts of anger, selfish ambition, dissension, division, envy, drunkenness, wild parties, and other sins like these. Let me tell you again, as I have before, that anyone living that sort of life will not inherit the Kingdom of God.
Galatians 5:19-21
Even now the ax of God’s judgment is poised, ready to sever the roots of the trees. Yes, every tree that does not produce good fruit will be chopped down and thrown into the fire.
Matthew 3:10
Nothing evil will be allowed to enter, nor anyone who practices shameful idolatry and dishonesty—but only those whose names are written in the Lamb’s Book of Life.
Revelation 21:27
“Therefore be imitators of God, as beloved children; and walk in love, just as Christ also loved you and gave Himself up for us, an offering and a sacrifice to God as a fragrant aroma. But immorality or any impurity or greed must not even be named among you, as is proper among saints; and there must be no filthiness and silly talk, or coarse jesting, which are not fitting, but rather giving of thanks. For this you know with certainty, that no immoral or impure person or covetous man, who is an idolater, has an inheritance in the kingdom of Christ and God. Let no one deceive you with empty words, for because of these things the wrath of God comes upon the sons of disobedience.”
Ephesians 5:1-6
the thing about Ephesians 5 is Paul is speaking to Children of God who are saved according to Ephesians 2.
A faithful, sensible servant is one to whom the master can give the responsibility of managing his other household servants and feeding them. If the master returns and finds that the servant has done a good job, there will be a reward. I tell you the truth, the master will put that servant in charge of all he owns. But what if the servant is evil and thinks, ‘My master won’t be back for a while,’ and he begins beating the other servants, partying, and getting drunk? The master will return unannounced and unexpected, and he will cut the servant to pieces and assign him a place with the hypocrites. In that place there will be weeping and gnashing of teeth.
Matthew 24:45-51 The servant of the master is referring to a servant of God.
All who are victorious will inherit all these blessings, and I will be their God, and they will be my children. “But cowards, unbelievers, the corrupt, murderers, the immoral, those who practice witchcraft, idol worshipers, and all liars—their fate is in the fiery lake of burning sulfur. This is the second death.
Revelation 21:7-8
“And although you were formerly alienated and hostile in mind, engaged in evil deeds, yet He has now reconciled you in His fleshly body through death, in order to present you before Him holy and blameless and beyond reproach- if indeed you continue in the faith firmly established and steadfast, and not moved away from the hope of the gospel that you have heard, which was proclaimed in all creation under heaven, and of which I, Paul, was made a minister.”
Colossians 1:21-23
“By this we know that we have come to know Him, if we keep His commandments. The one who says, "I have come to know Him," and does not keep His commandments, is a liar, and the truth is not in him; but whoever keeps His word, in him the love of God has truly been perfected. By this we know that we are in Him: the one who says he abides in Him ought himself to walk in the same manner as He walked.”
1 JOHN 2:3-6
“The word that came to Jeremiah from the LORD, saying, "Stand in the gate of the LORD'S house and proclaim there this word and say, 'Hear the word of the LORD, all you of Judah, who enter by these gates to worship the LORD!'" Thus says the LORD of hosts, the God of Israel, "Amend your ways and your deeds, and I will let you dwell in this place. Do not trust in deceptive words, saying, 'This is the temple of the LORD, the temple of the LORD, the temple of the LORD.' For if you truly amend your ways and your deeds, if you truly practice justice between a man and his neighbor, if you do not oppress the alien, the orphan, or the widow, and do not shed innocent blood in this place, nor walk after other gods to your own ruin, then I will let you dwell in this place, in the land that I gave to your fathers forever and ever. "Behold, you are trusting in deceptive words to no avail. Will you steal, murder, and commit adultery and swear falsely, and offer sacrifices to Baal and walk after other gods that you have not known, then come and stand before Me in this house, which is called by My name, and say, 'We are delivered!'-that you may do all these abominations? Has this house, which is called by My name, become a den of robbers in your sight? Behold, I, even I, have seen it, " declares the LORD.”
