Why do people labor for things that do not satisfy?

Isaiah 55:2 provocatively asks, 'Wherefore do you spend money for that which is not bread, and your labor for that which satisfies not?' This inquiry reflects the tendency of human nature to seek fulfillment in temporary, earthly pleasures rather than in the eternal satisfaction that comes from God. Sinful self-reliance leads individuals to chase after material possessions, accomplishments, and vain pursuits, which can never truly satisfy the deeper spiritual hunger of the soul. The Scriptures reveal that only through faith in Christ can true contentment and peace be found. When we rely on Christ, we cease from our fruitless labors and find rest in His sufficiency.
