1 But there were also false prophets among the people, even as there will be false teachers among you, who will secretly bring in destructive heresies, even denying the Lord who bought them, and bring on themselves swift destruction. 2 And many will follow their destructive ways, because of whom the way of truth will be blasphemed. (2 Peter 2:1–2, NKJV)
Peter’s warning makes it clear that what we believe and teach matters to God. Therefore, what Bible teachers teach us should matter. To think it does not matter to God what we believe “as long as we are sincere” flies in the face Peter’s admonition. The instruction of a false teacher is erroneous. His message is destructive and heretical and often is brought in secretly (cf. Jude 4). False teaching denies the Lord, who is the Truth, and in whose word we must abide (Jno. 14:6; 8:31-32). Peter emphasizes the danger of following error in verse 2. We cannot follow a destructive way without also being destroyed. False teaching is against “the way of truth.” When Christians follow it, others blaspheme (speak against) the truth. Peter did not teach unity in doctrinal diversity. Peter did not say a teacher is false only if his heart is insincere or deceptive. It is the false teaching that identifies the teacher as false (Gal. 1:6-9; 2 Jno. 9-11). Minimizing false teaching minimizes Peter’s warning and endangers souls. Truth sets us free, but error enslaves (Jno. 8:32).
