Note 12 at Mt. 24:31: Angels are created (Neh. 9:6; Col. 1:16) spirit beings (Ps. 104:4; Heb. 1:14) who are superior to man in might and power (Isa. 37:36; 2 Pet. 2:11; Rev. 20:1-2). Although their substance is spirit (1 Ki. 22:21; Ps. 104:4), they have oftentimes appeared in human form (Gen. 19:1-22; Jud. 6:11-22). They are holy (Mk. 8:38), elect (1 Tim. 5:21), and engaged in God's work (Ps. 103:20). Although heaven is their home (Mt. 18:10; Mk. 12:25; Lk. 1:19), they, nevertheless, are involved in God's service on earth (Heb. 1:14). In Genesis 28:12 and John 1:51, they are seen as ascending and descending between heaven and earth.

Some facts concerning angels are: they are not to be worshipped (Col. 2:18); they are innumerable (Heb. 12:22); they serve God's people (Acts 12:7-11; Heb. 1:14); they rejoice over the salvation of the lost (Lk. 15:10); they protect and deliver God's children (2 Ki. 6:17-18; Dan. 6:22; Acts 5:19); they observe the affairs of men (1 Cor. 4:9); they accompany the saints at death (Lk. 16:22); they neither marry nor are given in marriage (Mt. 22:30); they never die (Lk. 20:36); they excel in strength, do God's commandments, and obey His Word (Ps. 103:20); they accompany Christ at His return (Mt. 25:31); and they execute God's judgments (Mt. 13:39-42; see note 2 at Lk. 20:36, p. 381).
