Absolutely NObody has the authority to change the Gospel of Jesus Christ.  What He has stated is necessary for salvation is what it is, and if anyone preaches that this is anything else besides faith in Christ as the Son of God who died and rose from the dead, they are super wrong, my friend.  Speaking of wrong, Paul mentions how he did some things he shouldn’t have before he got saved.  What did he do?

-He was a thief-

-He persecuted Christians-

-He sacrificed children-

-He was in an immoral relationship-
