"He is proud, knowing nothing, but doting about questions and strifes of words, whereof cometh envy, strife, railings, evil surmisings," - 1 Tim 6:4
False teachers are puffed up with pride. The gospel of grace produces a humble spirit (Ephesians 3:8); but the doctrines of men (works and self-righteousness) fill the mind with pride, vanity, and self-esteem.
They really know nothing of spiritual things, of the gospel of Christ, but spend their time in controversy, disputes, and strife over words, laws, foolish and unanswerable questions. Their ministry produces envy and jealousy, quarrels and dissension, insults and slander, and evil suspicions. The true grace of God promotes peace in the home, in the church, between labor and management, and in the neighborhood (2 Tim 2:22-23; Romans 14:19).
Withdraw yourself from these men who are contentious and quarrelsome, who are always disputing and galling one another, provoking men to strife, envy, and anger. They are destitute of the truth of Christ and have not the Spirit of God.
