God-shaped hole suggests that every person has an emptiness in their soul or spirit that only God can fill. This idea is rooted in the innate longing of the human heart for something transcendent, something beyond itself. As stated in Ecclesiastes 3:11, God has placed "eternity in man's heart," and only God can satisfy this desire for eternity. Many people spend their lives trying to fill this void with temporary pursuits-such as work, family, or hobbies- but find these efforts ultimately unfulfilling. Even those who achieve worldly success, like Solomon, find that these pursuits do not satisfy the deeper longing for eternity and call it "vanity." The question then arises: if we have free will, why do we not choose God? Some, like St. Augustine and Robert Sapolsky, argue that our choices are constrained by our nature, questioning if true "free will" exists at all.
