Another gospel is the same as a false gospel or a gospel different from the one and only real one. Another gospel can be a popular teaching or one which is little known, but regardless, it claims to be the gospel of Jesus Christ, yet is counterfeit and therefore dangerous to SOULS. Another gospel is presented, even to Christians, as the real plan of salvation found in the Bible, but is demonically misrepresenting the truth of God and eternal life. In Paul’s day, it misled true Christians in the region of Galatia away from God and back into spiritual death as the victims fell from grace (Gal. 5:2-4). Paul furiously fought another gospel:
I marvel that ye are so soon removed from him that called you into the grace of Christ unto another gospel: Which is not another; but there be some that trouble you, and would pervert the gospel of Christ. (Gal 1:6,7, KJV)
Paul defended the true gospel and warned against the false in the strongest terms:
But though we, or an angel from heaven, preach any other gospel unto you than that which we have preached unto you, let him be accursed. As we said before, so say I now again, If any man preach any other gospel unto you than that ye have received, let him be accursed. For do I now persuade men, or God? or do I seek to please men? for if I yet pleased men, I should not be the servant of Christ. (Gal 1:8-10)
The gospel message must be accurate to bring about new creations in Christ. If not, it will be just another powerless gospel devoid of transforming power. Hence, one can go to hell just for preaching a false gospel and Paul knew that applied to him! All of the false religions preach another gospel – from Catholicism to Jehovah’s Witnesses toUniversalism, and the list goes on.
One false gospel out shines all the others though. It is once saved always saved. Again,once saved always saved is another gospel. It teaches the Christian has salvation in wickedness, minimizes and/or dismisses living holy in our day, misrepresents a conditional salvation and has spread like gangrene. Multitudes are in fiery torment at this moment because of this license for immorality. So, what is the gospel of Jesus Christ? Ponder especially 1 Cor. 15:1-4; Acts 20:21; 26:20; etc. It is a matter of eternal life or eternal death to know the truth from another gospel. God bless you.
