David, even with a limited understanding of astronomy, knew how infinite the heavens were. In Psalm 36:5 David uses the infiniteness of the heavens to describe God’s love for us, Your love, O Lord, reaches to the heavens, your faithfulness to the sky. It is this unfailing and endless love God has for each of us if we simply choose to believe and accept it. God cares for us more than we can ever imagine.
