Verse 4.— For if God spared not the angels that sinned. You know that God spared not the angels who rebelled. He subjected them to punishment. They were cast out of heaven and into darkness. They are bound with chains, or "pits of darkness," as the Revised Version has it, and are kept or reserved for judgment. This shows you, as one example, the certainty of punishment that awaits the false teachers and their followers. But I will give you other instances.
