"If anybody is preaching to you a gospel other than what you accepted, let him be eternally condemned!" - Galatians 1:9 (NIV)
You should be watchful about the sort of gospel that you embrace.
Paul cautioned Galatians about a few evangelists who were in the propensity for hawking 'an alternate gospel' which is 'extremely no gospel by any means' (see Galatians 1:6-7).
We have such ministers in our middle today.
To show how unsafe and undesirable their gospel is, Paul wished its vendors would be 'interminably censured!' unless they rapidly understand their imprudence and retouch their ways.
The merchants of such a gospel lead numerous astray...into judgment and otherworldly passing; this clearly is against God's arrangement for humankind!
This other gospel isn't, and will never be, to your greatest advantage! You have to see through it.
Action point [top priority]: Adopt the habit of verifying from the Bible every teaching that you receive from anybody, even from great men and women of God.
God Bless You
