(1.) Their nature. They are living creatures; they are the creatures of God, the work of his hands; their being is derived; they have not life in and of themselves, but receive it from him who is the fountain of life. As much as the living creatures of this lower world excel the vegetables that are the ornaments of earth, so much do the angels, the living creatures of the upper world, excel the sun, moon, and stars, the ornaments of the heavens. The sun (say some) is a flame of fire enfolding itself, but it is not a living creature, as angels, those flames of fire, are. Angels are living creatures, living beings, emphatically so. Men on earth are dying creatures, dying daily (in the midst of life we are in death), but angels in heaven are living creatures; they live indeed, live to good purpose; and, when saints come to be equal unto the angels, they shall not die any more, Luke xx. 36.
