The primary purpose for which they were created by God was, according to our text, to be servants (i.e., “ministers”) to those who are to inherit salvation. They are beings of great wisdom, “to know all things that are in the earth” (2 Samuel 14:20). Furthermore, they “excel in strength” (Psalm 103:20). They can travel at tremendous speeds, “being caused to fly swiftly” (Daniel 9:21). Furthermore, there exists “an innumerable company of angels” (Hebrews 12:22), so God is able to dispatch any necessary number of them to “do his commandments” (Psalm 103:20) on behalf of His people.
