Praise and worship is not only the work of men and angels, it is also the work of all creation. The heavens, the sun, moon, and stars that have no vocal cords are all admonished by the psalmist to praise the name of the Almighty God. We live in a universe where everyone and everything is involved in worship and praise to God. Surely the ones who have been afforded more grace than everything else should come up "light" in our praise. Always keep a word of praise in your heart!
Praise ye him, sun and moon: praise him, all ye stars of light. Praise Him, ye heavens of heavens, and ye waters that be above the heavens. Let them praise the name of the Lord: for he commanded, and they were created.
- Psalms 148:3-5
