1. Galatians 1:6-10

2.  Scripture says people would fall away.  “The time will come when they will not endure sound doctrine, but according to their own desires, because they have itching ears, they will heap up for themselves teachers; and they will turn their ears away from the truth, and be turned aside to fables” (2 Tim 4:3-4).  “There were also false prophets among the people, even as there will be false teachers among you” (2 Pet 2:1).

3. There is but one Gospel!

4. Galatians 1:6-10

5.  The Galatians were turning to a different gospel, which is not another gospel.  Paul uses two different Greek words—“different”/ “another.”  NIV: You “are turning to a different gospel—which is really no gospel at all.”

6.  If anyone preaches a different gospel, let him be eternally condemned.  This says preaching is nothing to play around with.  “My brethren, let not many of you become teachers, knowing that we shall receive a stricter judgment” (Js 3:1).

7.  God has given a message to be proclaimed.  “As the L ORD lives, whatever the L ORD says to me, that I will speak” (1 Ki 22:14).  “Preach the word!” (2 Tim 4:2).

8. There is but one Gospel!

9.  Believing anything but that one gospel can cost you your soul.  “Hymenaeus and Philetus are of this sort, who have strayed concerning the truth, saying that the resurrection is already past; and they overthrow the faith of some” (2 Tim 2:17-18).  “Whoever transgresses and does not abide in the doctrine of Christ does not have God” (2 Jn 1:9).

10. How should we respond?

11.  One: You need to check behind the preacher.  The Bereans “were more fair-minded than those in Thessalonica, in that they received the word with all readiness, and searched the Scriptures daily to find out whether these things were so” (Acts 17:11).  If you’re going to check behind the preacher: You need to bring your Bible. You need to pay attention.

12.  Two: You need to check yourself.  You need to check your Bible to make sure you believe what is right. 2 Tim 3:16-17. “His divine power has given to us all things that pertain to life and godliness, through the knowledge of Him who called us by glory and virtue” (2 Pet 1:3).  We need to study the Bible!

13.  Three: You must teach your children.  God wants parents to teach their children His truths. Deut 6:6-7. “Fathers, do not provoke your children to wrath, but bring them up in the training and admonition of the Lord” (Eph 6:4).  The world will not teach our children in the way they should go!

14.  Four: You must teach the truth to others.  So many want to do God’s will, but they are caught up in error.  We have a responsibility to teach. “Go into all the world and preach the gospel to every creature” (Mk 16:15). We’re to teach the one gospel to everyone. Do you know the gospel well enough to teach someone? Do you need to obey the one gospel this morning?
