How do we know that man has a void that can only be filled by God?

In Ecclesiastes 3:11, it is stated that God has placed eternity in the hearts of men. This 'God-shaped void' signifies that every person possesses an innate understanding that life extends beyond mere physical existence. Despite attempts to fill this emptiness through materialism or false religion, true fulfillment can only come from a relationship with God through Christ. The struggle to seek meaning highlights the necessity for divine intervention in filling this void. Romans 1:20 further supports this idea, affirming that God's invisible attributes are clearly seen, leaving mankind without excuse for failing to acknowledge their need for Him.
