Jude 15-21; "To execute judgment upon all, and to convince all that are ungodly among them of all their ungodly deeds which they have ungodly committed, and of all their hard speeches which ungodly sinners have spoken against him. These are murmurers, complainers, walking after their own lusts; and their mouth speaketh great swelling words, having men's persons in admiration because of advantage. But, beloved, remember ye the words which were spoken before of the apostles of our Lord Jesus Christ; how that they told you there should be mockers in the last time, who should walk after their own ungodly lusts. These be they who separate themselves, sensual, having not the Spirit. But ye, beloved, building up yourselves on your most holy faith, praying in the Holy Ghost, keep yourselves in the love of God, looking for the mercy of our Lord Jesus Christ unto eternal life."Verse 15 emphasizes ungodliness. These false ministers are the total opposite of what GOD is, and if we know what GOD is, what godliness is, then we can identify and avoid them. Jude then gives four more descriptors to help us identify false teachers: 1) They are discontented murmers and complainers. They always have something to gripe about, discontent with their lot in life, they find fault with everything, nothing is ever right for them. 2) They live to satisfy their every desire; a trait Jude has already explained thoroughly. 3) They speak bombastic bragging words and 4) they are respecters of persons, if it will benefit them. They will do anything to get ahead.
