Why is it important to watch for false teachers in the church?

The warning against false teachers is crucial as outlined in Acts 20:29-30, where Paul forewarns the elders about grievous wolves who will not spare the flock. These false prophets can arise from within the church, subtly distorting the truth and drawing disciples after themselves rather than following Christ. The importance of vigilance against false teachers cannot be overstated; they threaten the integrity of the gospel message. By keeping a watchful eye, congregations can ensure that the gospel of grace remains uncontaminated by human effort or works-based righteousness. This preservation of truth is essential for the spiritual health of the church.
