2 Peter 2:1–3 (ESV) — 1 But false prophets also arose among the people, just
as there will be false teachers among you, who will secretly bring in
destructive heresies, even denying the Master who bought them, bringing upon
themselves swift destruction. 2 And many will follow their
sensuality, and because of them the way of truth will be blasphemed. 3 And in their greed they will exploit you with false words. Their
condemnation from long ago is not idle, and their destruction is not asleep.
NOTE: Peter promises
there will be false teachers among you. So, they are not outside teachers whose
teaching is misleading people, but teachers within the church. They secretly
bring in destructive heresies--these are truths that destroy people rather than
build them up in the knowledge of God. They use sensuality, and an unique
"insight" that blasphemes truth (they know better). They are greedy
and gain from their false teaching either financially or in pride and status.
God promises to bring destruction upon them, which is why it is so important as
a teacher to be constantly evaluating what we teach. The best protection is
constant immersion in the word of God, and a deep and abiding relationship with
the savior. We need to be on the watch for new ideas that have no basis in
scripture, and especially if they violate other areas of scripture. The bible
is the standard for truth in all cases.
