When we go outside on a cloudless night and see the vastness of space and all the stars and galaxies, we can hear them proclaiming God's glory. When we hear of far away blackholes and beautiful nebulas, we can feel a sense of our smallness. Our God is speaking to us through all that he has made.
"The heavens declare the glory of God,
and the sky above proclaims his handiwork.
Day to day pours out speech,
and night to night reveals knowledge.
There is no speech, nor are there words,
whose voice is not heard." Psalm 19:1-2
