The fear of the LORD is the beginning of wisdom: and the knowledge of the holy is understanding (Proverbs 9:10). If mankind rejects this truth, he will find himself seeking wisdom and knowledge in other sources. This is total foolishness considering that God Himself is the ultimate source of all knowledge and wisdom. There are two sets of triads in this session, the first relating to whom the epistle is addressed and the second related to moral, social and doctrinal separation. Many churches in America have given themselves over to doctrinal apostasy having first chosen to ignore moral and social separation. The real enemy is Satan who has cunningly deceived many saints and churches leaving the door open for the infiltration of apostates. We must be vigilant in contending for the faith once delivered to the saints.
