But there were also false prophets among the people, just as there will be false teachers among you. They will secretly introduce destructive heresies, even denying the sovereign Lord who bought them—bringing swift destruction on themselves.2 Peter 2:1 NIV
Peter warns us here about false teachers who proclaim destructive heresies. Doctrines that are unbiblical and detrimental to our walk with Christ. You don’t have to look very far today to find teachers who are proclaiming a gospel other than what is taught in the Scripture.
So how can you tell if it is a false teacher you are hearing? Sometimes their error is obvious, while other times it is more subtle. The best way to protect yourself from them is to know the Scriptures. Be like the Bereans (Acts 17:11) and study the Scriptures. If someone teaches contrary to it, or introduces other writings to support their teachings, you should reject them. Another way is to look to see who is at the center of their teaching and ‘ministry’? Is it Christ? Or are they the center of attention? If Christ is not the focus, then you should not get caught up in their ‘ministry’ (John 3:30). And, finally, let the Holy Spirit lead you into the truth (John 16:13). Don’t be led astray from the true faith by those who are facing destruction.
Are you a teacher? Be sure that your teaching is grounded in the Bible, the word of God. Don’t be guilty of leading others astray. The consequences are devastating, both to you and to those you have led astray (James 3:1).
