Who maketh his angels spirits; or wields, for the word means either. Angels are pure spirits, though they are permitted to assume a visible form when God desires us to see them. God is a spirit, and he is waited upon by spirits in his royal courts. Angels are like winds for mystery, force, and invisibility, and no doubt the winds themselves are often the angels or messengers of God. God who makes his angels to be as winds, can also make winds to be his angels, and they are constantly so in the economy of nature. His ministers a flaming fire. Here, too, we may choose which we will of two meanings: God's ministers or servants he makes to be as swift, potent, and terrible as fire, and on the other hand he makes fire, that devouring element, to be his minister flaming forth upon his errands. That the passage refers to angels is clear from Heb 1:7; and it was most proper to mention them here in connection with light and the heavens, and immediately after the robes and paltree of the Great King. Should not the retinue of the Lord of Hosts be mentioned as well as his chariot? It would have been a flaw in the description of the universe had the angels not been alluded to, and this is the most appropriate place for their introduction. When we think of the extraordinary powers entrusted to angelic beings, and the mysterious glory of the seraphim and the four living creatures, we are led to reflect upon the glory of the Master whom they serve, and again we cry out with the psalmist, "O Lord, my God, thou art very great."
