I found this gem in Spurgeon:
This submission to law is praise. Obedience is homage; order is harmony. In this respect the praise rendered to Jehovah from the “bodies celestial” is absolutely perfect. His almighty power upholds all things in their spheres, securing the march of stars and the flight of seraphs; and thus the music of the upper regions is never marred by discord, nor interrupted by destruction. The eternal hymn is for ever chanted; even the solemn silence of the spheres is a perpetual Psalm.
