Psalms 148:3

We, in this dark and sinful world, know little of the heavenly world of light. But we know that there is above us a world of blessed angels. They are always praising God, therefore the psalmist shows his desire that God may be praised in the best manner; also we show that we have communion with spirits above, who are still praising him. The heavens, with all contained in them, declare the glory of God. They call on us, that both by word and deed, we glorify with them the Creator and Redeemer of the universe.

Praise ye him, sun and moon: praise him, all ye stars of light. The Psalmist enters into detail as to the heavenly hosts. As all, so each, must praise the God of each and all. The sun and moon, as joint rulers of day and night, are paired in praise: the one is the complement of the other, and so they are closely associated in the summons to worship. The sun has his peculiar mode of glorifying the Great Father of lights, and the moon has her own special method of reflecting his brightness. There is a perpetual adoration of the Lord in the skies: it varies with night and day, but it ever continues while sun and moon endure. There is ever a lamp burning before the high altar of the Lord. Nor are the greater luminaries allowed to drown with their floods of light the glory of the lesser brilliants, for all the stars are bidden to the banquet of praise. Stars are many, so many that no one can count the host included under the words, "all ye stars"; yet no one of them refuses to praise its Maker. From their extreme brilliance they are fitly named "stars of light"; and this light is praise in a visible form twinkling to true music. Light is song glittering before the eye instead of resounding in the ear. Stars without light would render no praise, and Christians without light rob the Lord of his glory. However small our beam, we must not hide it: if we cannot be sun or moon we must aim to be one of the "stars of light", and our every twinkling must be to the honour of our Lord.
