7 not that there is another gospel, but there are some who are troubling you and want to change the good news about the Messiah.
8 But even if we or an angel from heaven should preach to you a gospel other than what we have preached to you, a curse be on him!
9 As we have said before, I now say again: If anyone preaches to you a gospel contrary to what you received, a curse be on him!
10 For am I now trying to win the favor of people, or God? Or am I striving to please people? If I were still trying to please people, I would not be a slave of Christ.
11 Now I want you to know, brothers, that the gospel preached by me is not based on human thought.
12 For I did not receive it from a human source and I was not taught it, but it came by a revelation from Jesus Christ.
13 For you have heard about my former way of life in Judaism: I persecuted God’s church to an extreme degree and tried to destroy it.
