Reject the gospel different from the one we accepted, different from our Byble says

 2 Corinthians 11:1-15

For if someone comes to you and preaches a Jesus other than the Jesus we preached, or if you receive a different spirit from the Spirit you received, or a different gospel from the one you accepted, you put up with it easily enough.

I may indeed be untrained as a speaker, but I do have knowledge. We have made this perfectly clear to you in every way.

I have kept myself from being a burden to you in any way, and will continue to do so. As surely as the truth of Christ is in me, nobody in the regions of Achaia will stop this boasting of mine.  Why? Because I do not love you? God knows I do!

It is not surprising, then, if his servants also masquerade as servants of righteousness. Their end will be what their actions deserve.

Why?

Paul reminded Christians in the Corinthian church, Don't be deceived by the word or false talk that misleads their faith and way. For the servants also masquerade as servants of righteousness. 

Getting the higher honors and getting more benefits from people who are false Christians.

How?

We are eager to honor the Holy Name of the Lord, but we also need to be aware of the false talk and words different from what we have learned from the beginning.
