104:4 Who {b} maketh his angels spirits; his ministers a flaming fire:
(b) As the prophet here shows that all visible powers are ready to serve God: so in He 1:7 the angels also, are obedient to his commandment.
104:4 Spirits - Of a spiritual or incorporeal nature, that they might be fitter for their employments. Fire - So called for their irresistible force and agility, and fervency in the execution of God's commands.
104:1-9 Every object we behold calls on us to bless and praise the Lord, who is great. His eternal power and Godhead are clearly shown by the things which he hath made. God is light, and in him is no darkness at all. The Lord Jesus, the Son of his love, is the Light of the world.
