The teaching of eternal security always, with no exception, allows for a person previously saved to become immoral in various ways and still believe, even while unrepentant, he is still retaining his salvation and remaining on the road to God's paradise kingdom. While there are some eternal security proponents that will say if one turns to immorality he was never really saved, please know that is only their occasional-answer and is not consistent with their understanding of King David remaining saved while in both adultery and murder. (David is only one example.) Hence, all eternal security people, including this group, allows for a person previously saved to turn to wickedness and erroneously think he has retained his salvation.
Do not be deceived: God cannot be mocked. A man reaps what he sows. The one who sows to please his sinful nature, from that nature will reap destruction; the one who sows to please the Spirit, from the Spirit will reap eternal life. Let us not become weary in doing good, for at the proper time we will reap a harvest if we do not give up. Therefore, as we have opportunity, let us do good to all people, especially to those who belong to the family of believers (Gal. 6:7-10).
For a person to think he can reap eternal life after sowing to please the sinful nature is both an attempt to mock God and a deadly deception about salvation from a real grace teacher, yet it is the very deception the eternal security proponent of our day is in. Paul told the same churches a similar truth about this:
The acts of the sinful nature are obvious: sexual immorality, impurity and debauchery; idolatry and witchcraft; hatred, discord, jealousy, fits of rage, selfish ambition, dissensions, factions and envy; drunkenness, orgies, and the like. I warn you, as I did before, that those who live like this will not inherit the kingdom of God (Gal. 5:21).
Paul warned those who had been saved about immorality stopping them from inheriting God's Kingdom. His message to the Corinthians and Ephesians was similar:
Do you not know that the unrighteous will not inherit the kingdom of God? Do not be deceived. Neither fornicators, nor idolaters, nor adulterers, nor homosexuals, nor sodomites, nor thieves nor the covetous, nor drunkards, nor revilers, nor extortioners will inherit the kingdom of God (1 Cor. 6:9,10, NKJV).
For of this you can be sure: No immoral, impure or greedy person—such a man is an idolater—has any inheritance in the kingdom of Christ and of God. Let no one deceive you with empty words, for because of such things God's wrath comes on those who are disobedient. Therefore do not be partners with them (Eph. 5:5-7).
Dear children, do not let anyone lead you astray. He who does what is right is righteous, just as he is righteous. He who does what is sinful is of the devil... (1 John 3:7,8).
James follows along with a similar truth and warning about the lethal dangers of sin:
But each one is tempted when, by his own evil desire, he is dragged away and enticed. Then, after desire has conceived, it gives birth to sin; and sin, when it is full-grown, gives birth to death. Don't be deceived, my dear brothers (James 1:14-16).
When James wrote his epistle there were no chapter and verse divisions in Scripture. These were given hundreds of years later. It is clear that James cited his don't be deceived warning about the deadly effects of sins when we realize the first part of verse 16 goes with verses 14 and 15.
These warnings throughout the New Testament pertaining to the effects of sin comprise the majority of warnings in the NT about deception regarding immorality. Since each is destructive to eternal security, one must wonder how so many can remain deluded about salvation. It is one thing to have been in deception in the past, but it is an entirely different thing to remain in it after the clarity of Scripture has been presented.
There is no justifiable way any eternal security proponent can say he never knew about the spiritually fatal dangers of sin after reading the aforementioned Scriptures although multitudes dangerously and willfully reject the Bible's clear message in favor of a damnable fairytale to their own detriment. May many read these warnings about deception and take them to heart by turning from sin and from the teaching of eternal security.
