When men follow after vanity, they themselves become vain. An individual must make a conscious decision to turn from walking after the Lord to pursue vanity (Jeremiah 2:5). Those who follow after vanity are void of understanding (Proverbs 12:11) and end up in poverty (Proverbs 28:19), sometimes both spiritually and physically. David expressed his concern in this area when he said, “I have not sat with vain persons” (Psalm 26:4). He knew the danger of following vanity and declared that he refused even to sit with vain persons. In Psalm 119:37, the penman pleaded with the Lord for help in turning away his eyes from beholding vanity. God desires and wills for the saints of God to cease from following after vanity.
The unity of believers is likened to a cord woven together. Like a threefold cord, unified believers are stronger and better able to endure the attacks from their enemies (Ecclesiastes 4:12). In Proverbs 6:16-19, the Lord gives a list of things He hates, one of which is when a man sows “discord among brethren.” What does it mean to sow “discord”? Perhaps the illustration given above sheds the necessary light for an answer. When believers are united, they are like multiple cords woven together. When someone sows discord, he attempts to undo or “discord” the threefold cord destroying the unity. Believers void of unity are weaker and more vulnerable to the attacks of the enemy.
