In Psalm 19:1, 2 David had said that the heavens speak of the glories of God, yet, David also wrote,
There is no speech nor language
Where their voice is not heard.
Obviously, the heavens do not come out and speak as we do, but what they reveal is so clear that they could not have said more if they had used human language to speak to us of God.
What do you hear when you observe the heavens or any part of nature?
