So it is possible to live like an unbeliever, to sin continually and yet still be saved? I don't think so!
Romans 6:1-2, 14. 'What shall we say then? Shall we continue in sin that grace may abound? Certainly not! How shall we who died to sin live any longer in it?...............For sin shall not have dominion over you, for you are not under law but under grace.'
Of course we are saved by grace through faith, but we are saved from our sins, not in them. The believer is born again by the Holy Spirit of God unto good works, not unto evil ones. Notice that Paul says that for the very reason that Christians are not under law but under grace, sin shall not have dominion over us. Not ought not; not even must not; but shall not. It's absolutely certain.
So what do we say when a professing Christian is living a life where there is continually nothing but sin and carnality to be seen? We have to say that he in not a Christian; that he has not been born from above and that he is in need of conversion. 'Do you not know that the unrighteous will not inherit the kingdom of God? Do not be deceived!' (1 Cor. 6:9).
BTW, it appears that the immoral man of 1 Cor. 5 was brought to repentance (2 Cor. 3-11).
Paul says "it is possible to live like an unbeliever, to sin continually and yet still be save"
1 Corinthians 3:13 Every man's work shall be made manifest: for the day shall declare it, because it shall be revealed by fire; and the fire shall try every man's work of what sort it is.
14 If any man's work abide which he hath built thereupon, he shall receive a reward.
15 If any man's work shall be burned, he shall suffer loss: but he himself shall be saved; yet so as by fire.
This says a believer can gain nothing but wood, hay and straw, that is do no good works for God, how does one not do good works if they are truly saved. Those who say you will produce fruit for God if your saved need to answer how a believer can receive only wood, hay and straw and yet still be saved, yet so as through the fire. This is a carnal Christian one who doesn't walk after the Spirit. to walk after the Spirit means you are filled that is controlled by Him and when under His influence and control you produce good works. Paul says that a believer can suffer an eternal loss at the BEMA seat Judgment and still be saved very clear.
