“Their eyes, full of adultery, never stop sinning; they entice unstable people. They have trained their hearts for greed, these cursed children!”
2 Peter 2.14
False teachers aren’t good moral people who happen to get some things wrong. Their whole orientation is toward evil, seeking their own gain.
Some people work hard at being evil. They exercise themselves to pursue their own interests. They are also strong recruiters. Do I recognize such people for who they really are?
