Paul didn't mince any words in telling the Galatian churches that there is only one gospel and that if anyone else is preaching a gospel, other than the one they accepted through Paul's evangelism, that the consequence is condemnation.
I know this sounds harsh, but many people want to preach a gospel that isn't the one Jesus taught and these gospels don't lead you to eternal life through Jesus Christ. False gospels lead to death and Jesus' gospel leads to eternal life. It is life and death for you and I to know the truth.
You don't have to earn your salvation.
Salvation is a free gift because Jesus already paid the price. My NIV Disciple's Study Bible states it this way on page 1490:
People still find it difficult to accept salvation as a free gift. They want to earn it, so they develop a code or ritual to justify themselves. Even more sadly, they fall prey to cults and sects which have an "aura of holiness" about them because they emphasize some kind of legal regimen which requires discipline...It is his (Jesus') crucifixion that sets us free to serve Him in love-not anything we have done, are doing, or will do.Brothers and sisters, don't listen to false gospels and preaching.
Know what your bible says. Don't use the excuse that man interpreted God's divinely inspired word into different versions and now it isn't God's word. That is the deceiver trying to keep you from the truth of God's word.
God's Divinely Inspired Words Have Not Been Changed
Use a parallel bible app, bible study website, and bible commentaries to learn that the original Greek and Hebrew has not been warped. For several years, I use biblehub.com to compare the different bible editions with Strong's Greek and Hebrew translations. God's original word has not been changed from the original, divinely inspired writings.
