Rising Joy, by Vicki Matheny
Now this matter arose because of the false brothers with false pretenses who slipped in unnoticed to spy on our freedom that we have in Christ Jesus, to make us slaves. But we did not surrender to them even for a moment, in order that the truth of the gospel would remain with you. Galatians 2.4-5
Sometimes you have to take a stand. You have to defend the truth against people who come into the meeting either twisting the truth or with false intentions. Their desire is not to build up a congregation. It is to distort and divide.
Paul called such people false brethren. These do not enter a place speaking their falsehoods clearly. Most often they slip in without anyone knowing the damage that is about to be done. Their teachings come out a little at a time, many times in the form of doubts and questions. Paul said their aim was to make slaves. In the Galatian churches, it was the teaching that to be a good Christian, you have to also follow the law of Moses.
Truth is important. There is only one source of that truth, God’s word. We need to be diligent to know what it says and to understand what it means. Paul stood firm in his defense of the gospel. We need to do the same.
Do you know the word well enough to know when someone is teaching something that is contrary to truth? If not, why not? Peter said that we need to be prepared to give answers to questions about our hope, 1 Peter 3.15. That also applies to defending the truth.
