Paul warns in his letters of those who would come and preach " another gospel"
2Co_11:4 For if he that cometh preacheth another Jesus, whom we have not preached, or if ye receive another spirit, which ye have not received, or another gospel, which ye have not accepted, ye might well bear with him.
Stop and think here for a moment as to what gospel you are trusting for your salvation.
Paul marveled at believers even who were so soon removed from the gospel they believed at in at the outset.
Gal_1:6 I marvel that ye are so soon removed from him that called you into the grace of Christ unto another gospel:
Gal_1:7 Which is not another; but there be some that trouble you, and would pervert the gospel of Christ.
If you have are not trusting Paul's gospel : 1 Corinthians 15: 3,4. You are in a bad place.
The gospel can be corrupted by just one word.
I have heard people preach " Christ died on the cross was buried and rose again"
In the light of the gospel according to the text it says " Christ died for our sins...
1Co 15:3 For I delivered unto you first of all that which I also received, how that Christ died for our sins according to the scriptures;
So according to them Christ did not die for our sins, this is how they corrupt the gospel and preach " another gospel"
Beware of those who dont preach Paul's gospel " according to the scriptures"
It has to be word for word as it is written.
1Co 15:3 For I delivered unto you first of all that which I also received, how that Christ died for our sins according to the scriptures;
1Co 15:4 And that he was buried, and that he rose again the third day according to the scriptures:
