But there were also false prophets among the people, just as there will be false teachers among you. They will secretly bring in destructive heresies, even denying the Master who bought them, and will bring swift destruction on themselves. Many will follow their unrestrained ways, and the way of truth will be blasphemed because of them. They will exploit you in their greed with deceptive words. Their condemnation, pronounced long ago, is not idle, and their destruction does not sleep.
Every day we must watch out for the children of the devil, the twisters of Scripture, the false prophets; for they are the devils Pied Pipers who will lead the weak away and bring death to so many. We must arm ourselves with the word of God so that we know when a teacher speaks falsely; we must test all against Scriptures, for the Scriptures do not lie, only the mouth of man does. If a prophet comes and says one thing, but it does not come to fruition, that prophet is false and a liar; if the prophet speaks against what is written in Scripture, that prophet is against the Lord and is false; these are the prophets of the devil, not the Lord.
Above all, read the Scriptures so that you are armed for the battle we face daily; for an unarmed soldier is just a casualty waiting to happen.
