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 book of Ecclesiastes contains documentation of Solomon’s life experiment apart from God. He examined the worth of subjects involving happiness, wealth, labour, and death. Ultimately, he concluded that life “under the sun” (Ecclesiastes 1:14) was vanity. The word vanity means empty or meaningless. Though Solomon wrote extensively concerning vanity, he was not the only person in the Bible to declare the vanity of life. In fact, Solomon’s father David declared that “every man at his best state is altogether vanity” (Psalm 39:5). King David added that if both men of high and low degree were laid in a balance together, they would be “lighter than vanity” (Psalm 62:9). Thus, regardless of worldly accomplishments and accolades, a life void of God remains meaningless.
God knows everything about everything, yet Christians sometimes act as though He has some debilitating limitations. Once again, the Bible shines the light of truth upon the matter. It reveals that He is great, “and of great power: his understanding is infinite” (Psalm 147:5). In fact, His eyes “are in every place, beholding the evil and the good” (Proverbs 15:3). In other words, there is nothing that escapes the knowledge and attention of God. This includes the good and the bad! The Son of God proclaimed to the church at Thyatira that He knew their works, charity, service, faith, and patience. He too knows about the level of a man’s faith! He knows the content, strength, and reality of that faith. A man can and will fool others and frequently even deceives himself (Jeremiah 17:9), but he has no capacity to mislead God. The Lord knows those who believe and accept His word as the perfect word of God and He is not unrighteous to forget (Hebrews 6:10).
