Why is it vital to understand the concept of foolishness in order to properly and profoundly appreciate the gospel?

[Austin]

Born foolish properly sets the stage that our hearts are “naturally” in a direction away from God. This being the case we have no option but to learn how to get our needs met in our own power. The Gospel rescues us from this destructive independence by bringing us to the One who made us, knows us, and has purpose for us. More than that, we were created to only find fulfillment in KNOWING HIM. So apart from Him there can be no true satisfaction.
