97:2-5 These verses reveal the appearance of the Lord in terms similar to other visions God gave His prophets (cf. Isa. 6:1-4; Ezek. 1; Rev. 1). The psalmist's words describe God's glory in figurative language. Clouds and thick darkness picture awesome power (cf. Deut. 4:11; 5:22-23; cf. Zech. 14:6-7). Fire represents God's consuming judgment (cf. Heb. 12:29). Elsewhere in Scripture the shaking of mountains announced the Lord's coming to earth (Exod. 19:18; cf. Mic. 1:4; Nah. 1:5).
97:6-9 When He comes to reign the heavens will announce His arrival (cf. Rev. 19:11). Everyone will see Him descend (Zech. 12:10). In view of this revelation, idol worshippers should realize their folly. The psalmist called all judges ("gods") to worship Yahweh. God's people can rejoice because He will rule over all the earth one day.
