2 Corinthians 11:2-4

For I am jealous for you with godly jealousy, because I promised you in marriage to one husband, to present you as a pure virgin to Christ.  But I am afraid that just as the serpent deceived Eve by his treachery, your minds may be led astray from a sincere and pure devotion to Christ.  For if someone comes and proclaims another Jesus different from the one we proclaimed, or if you receive a different spirit than the one you received, or a different gospel than the one you accepted, you put up with it well enough!

Paul will not tolerate false gospels. Paul being jealous for the church as Corinth means that he wants to protect them from being led astray, and is fervent about encouraging them to stand firm in Christ Jesus. As the body of Christ we must be ever discerning, and continually in prayer about the messages we hear, and about the message we are displaying through our lives lived for Christ. Holy Spirit, protect and guide us, guard our hearts and our minds and strengthen us to stand firm in our faith in the one, true, living God who saved us through His Son Jesus.
