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. And many will follow their sensuality, and because of them the way of truth will be blasphemed. 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.
Comment: History tends to repeat itself. There were, there are and there will be teachers who for various reasons will seek to deny and alter the truth of the gospel revealed by God. Plausible heresies, straight out denying of the person of Jesus, seeking personal gain, justifying sensual sins, are dangled in front of the true people of God to lead them into error. Their purpose is paraded as to make being a Christian more acceptable to the masses. Their end result, while having led some astray, is condemnation and destruction by God. I expect Peter to follow on with some examples of how God deals with such false teachers!
Prayer: Help me to discern error and avoid it like poison!
