The phrase "desire fails" is derived from the book of Ecclesiastes, specifically Ecclesiastes 12:5, which reads in the Berean Standard Bible : "when men fear heights and dangers in the streets, when the almond tree blossoms, the grasshopper drags itself along, and desire fails. For then man goes to his eternal home and mourners walk the streets." This passage is part of a poetic description of the aging process and the inevitable decline that accompanies it, culminating in death.

In the context of Ecclesiastes, "desire fails" is emblematic of the waning of human passions and appetites as one grows older. The Preacher, traditionally understood to be Solomon, uses vivid imagery to convey the frailty and transience of human life. The failing of desire is not merely a physical decline but also symbolizes the diminishing of earthly pursuits and pleasures that once captivated the heart.

From a theological perspective, this decline serves as a poignant reminder of the vanity of worldly desires and the ultimate futility of seeking fulfillment in temporal things. Ecclesiastes frequently emphasizes the theme of "vanity" or "meaninglessness" of life under the sun, apart from a relationship with God. The failing of desire, therefore, can be seen as an invitation to reorient one's focus from earthly to eternal matters.

In the broader biblical narrative, the concept of desire is multifaceted. While human desires can lead to sin and separation from God, as seen in the fall of man (Genesis 3), they can also reflect a longing for righteousness and communion with the Creator. Psalm 37:4 encourages believers to "Delight yourself in the LORD, and He will give you the desires of your heart." This suggests that when one's desires align with God's will, they are not only legitimate but also fulfilled by Him.

The New Testament further develops this theme by urging believers to set their minds on things above (Colossians 3:2) and to seek first the kingdom of God (Matthew 6:33). The failing of earthly desires, as described in Ecclesiastes, can thus be seen as a natural progression towards a deeper spiritual maturity, where one's ultimate desire is for God Himself.

In practical terms, the recognition that "desire fails" can lead to a life of greater contentment and peace. As believers age and experience the decline of physical and material desires, they are encouraged to find their satisfaction in the eternal promises of God. The Apostle Paul exemplifies this attitude in Philippians 4:11-13 , where he writes, "I have learned to be content regardless of my circumstances... I can do all things through Christ who gives me strength."

In summary, the phrase "desire fails" in Ecclesiastes serves as a sobering reflection on the brevity and limitations of human life. It challenges individuals to consider the fleeting nature of earthly desires and to seek fulfillment in a relationship with God, who alone can satisfy the deepest longings of the heart.
