What does the Bible say about the role of false teachers?

The scriptures speak clearly about the dangers of false teachers, as seen in Isaiah 56:10. These watchmen are described as blind, ignorant, and unable to provide guidance, ultimately leading the people astray with false promises. They promote a works-based righteousness, misleading believers into thinking that they can achieve favor with God through their efforts. This is detrimental to the faith, as true peace and salvation are found in Christ alone, not in the deceptive teachings of those who do not point to Him.
