David Brainerd emphasizes the notion that true happiness cannot be sourced from worldly possessions or experiences. Instead, he urges individuals to place their hope in God, who offers a deeper and more lasting fulfillment. This perspective suggests that while the world may offer temporary joys, they are fleeting compared to the enduring happiness that faith in God can provide.

In "Seeing the Unseen," author Randy Alcorn echoes this sentiment, reminding readers that faith and spiritual connection are essential for a truly happy life. By focusing on what is eternal and divine, rather than on the transient pleasures of life, individuals can find a more profound sense of joy and purpose. Alcorn's message encourages a shift in focus from the material to the spiritual for lasting contentment.
