First, I believe Eternal Security ultimately teaches that God's grace is a license for immorality on some level. However, the Bible condemns the thinking that we can turn God's grace into a license for immorality, though.
"For certain individuals whose condemnation was written about long ago have secretly slipped in among you. They are ungodly people, who pervert the grace of our God into a license for immorality and deny Jesus Christ our only Sovereign and Lord." (
Jude 1:4 NIV).
How do they deny Him?
By their lack of works (of course):
"They profess that they know God; but in works they deny
him, being abominable, and disobedient, and unto every good work reprobate." (Titus 1:16).
But the true grace of God teaches us to deny ungodliness and that we should live soberly, godly, and righteously in this present world.
11 "For the grace of God that bringeth salvation hath appeared to all men,
12 Teaching us that, denying ungodliness and worldly lusts, we should live soberly, righteously, and godly, in this present world;" (Titus 2:11-12).
Second, I am not suggesting that our fellows CF poster who started this thread should not try to witness the truth to her. In fact, I already said that he should tell her the reason why he is breaking it off. He should say that he believes Jesus is God and that he believes in the resurrection as a necessary part of salvation. But chances are that even if he were to witness to her, it is a very slim chance that she would accept what he is saying with the Bible (even if he were to do so). He should not stay in the relationship with a woman who is so against what the Bible says because it could influence him in the wrong way. Now, if they are already married that is a different matter. But this man has a choice to either choose a Bible believing Godly woman or he can choose this woman who denies that Jesus is God and who denies the resurrection. That to me is not good. So to let this woman go is not cold hearted in any sense of the word and it has nothing to do with God's saving grace. God's saving grace is there for people who honestly want to repent and to follow Jesus. Jesus's gift (Which is Himself - John 3:16) is not so that we can live for ourselves. We are not our own lords and masters. For Jesus said, "Why do you calle me, Lord, Lord, if you do not do what I say?" (Luke 6:46).
