W-O-R-K-S produces salvation. This is the false gospel separating the gospel of grace from every other religion of the world. "
Moreover, brethren, I declare unto you the gospel which I preached unto you, which also ye have received, and wherein ye stand;3 For I delivered unto you first of all that which I also received, how that Christ died for our sins according to the scriptures;4 And that he was buried, and that he rose again the third day according to the scriptures:" (1 Corinthians 15:1,3-4). This message is simple, but many "religionists" of the world will add conditions to the message. Paul made it clear, there are basically two gospels, one is of this world and is "works", this is every false religion, the other is from heaven above and is by "grace". "And if by grace, then is it no more of works: otherwise grace is no more grace. But if it be of works, then it is no more grace: otherwise work is no more work" (Romans 11:6). Those seeking to work their way into heaven are under the curse of the law and give evidence that they are unsaved, this is why Paul declared plainly "Now to him that worketh is the reward not reckoned of grace, but of debt." (Romans 4:4) Ask yourself is it works or grace, it can't be both. This is how one can tell the true gospel from a false gospel..
