I'm So Frustrated at How Some People Continue to Teach the Heresy of Fruitless Christianity

If people who teach salvation by works or add works to salvation makes me dizzy then I have to address people who teach the heresy of fruitless Christianity. These bunch of people teach that somebody can get saved and still remain the same. Folks, that teaching is 100% not biblical. I agree with them that salvation can't be lost but there's a difference between a person who's already once saved always saved vs. a person who has some false assurance they're once saved always saved.

Do you want to know why I reject the heresy of changeless Christianity? Let me cite some of these verses that warn people of the truth that you can't be saved and still remain the same:
Matthew 1:21 - "And she shall bring forth a son, and thou shalt call His name Jesus: for He shall save His people from their sins."
Matthew 7:16-20 - "Ye shall know them by their fruits. Do men gather grapes of thorns, or figs of thistles? Even so every good tree bringeth forth good fruit; but a corrupt tree bringeth forth evil fruit. A good tree cannot bring forth evil fruit, neither can a corrupt tree bring forth good fruit. Every tree that bringeth not forth good fruit is hewn down, and cast into the fire. Wherefore by their fruits ye shall know them."
Romans 3:31 - "Do we then make void the law through faith? God forbid: yea, we establish the law."
1 Corinthians 6:11 - "And such were some of you: but ye are washed, but ye are sanctified, but ye are justified in the name of the Lord Jesus, and by the Spirit of our God." 
Ephesians 2:10 - "For we are His workmanship, created in Christ Jesus unto good works, which God hath before ordained that we should walk in them."
Titus 2:11-14 - "For the grace of God that bringeth salvation hath appeared to all men, teaching us that, denying ungodliness and worldly lusts, we should live soberly, righteously, and godly, in this present world; looking for that blessed hope, and the glorious appearing of the great God and our Saviour Jesus Christ; who gave Himself for us, that He might redeem us from all iniquity, and purify unto Himself a peculiar people, zealous of good works."

I've already shown those verses yet they still continue to insist in their heresy. The verses are spelled out in simple English that salvation brings a changed life. Yet these proponents of the heresy of fruitless Christianity still teach that you can get saved and still remain the same. Their doctrine is a complete attack on the holiness of God and the power of His grace to change people for the better. If you're truly once saved always saved then your life ought to show it. If you're truly secure in Christ then God's grace will make you live soberly, righteously and properly in this present world. You have power against sin by the grace of God. 

I really want to tell people who think they're saved and can live in sin all they want that they're living in false security not eternal security. The doctrine of eternal security also shows that if you're truly saved then you're going to endure to the end in the long run (1 John 2:19). You may not be perfect (yet), you may fall away but you can't completely fall away. On the other hand, people who aren't saved are just sit-ins. I have no reason to believe Judas Iscariot was ever saved or lost his salvation but that he was never saved to start with. Matthew 7:23 also warns that such people are also doers of iniquity which shows they weren't saved to start with. I have no reason to believe that people who say they're saved but live in such flagrant sin are truly saved. Such people are just as lost as people who trust in their own inherent righteousness for salvation.

Can a Christian fall into sin and carnality? There's no doubt that can happen for a season. 1 John 1:8 says that if we say we have no sin then the truth is not in us. But can a Christian still fall into sin and carnality indefinitely? The answer is no. God's grace is greater than sin and a Christian can never enjoy sin. Hebrews 12:5-7 warns and guarantees of the loving chastising of the Father towards His own. There's no way that a Christian can still live like the rest of the world. True conversion may not be instantaneous to glorification. It has the slow and painful process of sanctification but even the most immature believer cannot love sin and they dread to sin. Only fake converts teach that they have a license to sin. Those who are truly converted continue to love righteousness and hate sin.
