15 Some men came down from Judea and began to teach the brothers: “Unless you are circumcised according to the custom prescribed by Moses, you cannot be saved!” 2 But after Paul and Barnabas had engaged them in serious argument and debate, the church arranged for Paul and Barnabas and some others of them to go up to the apostles and elders in Jerusalem concerning this controversy.
Some Christians don’t like to debate (political correctness) or think that it is unBiblical. A debate for the sake of strife is wrong but for the sake of the truth is commanded in Jude 1:3. We must always defend the truth with gentleness and meekness.
Those who love the truth will defend it and live by it. Those who don’t love the truth will allow those in error to continue on their way to destruction.
