1 The Lord is king, he is robed in majesty;
the Lord is robed, he is girded with strength.
He has established the world; it shall never be moved;
2 your throne is established from of old;
you are from everlasting.
3 The floods have lifted up, O Lord,
the floods have lifted up their voice;
the floods lift up their roaring.
4 More majestic than the thunders of mighty waters,
more majestic than the waves[a] of the sea,
majestic on high is the Lord!
5 Your decrees are very sure;
holiness befits your house,
O Lord, forevermore.
Imagery of God as a king and ruler are common in the Christian church. In fact, at the front of our own church, on the alter, is an inscription in Greek letters that translates to "Jesus Christ Conquers." High above the alter is a carving of a shield and a robe.
These are images of and words of rulers and kings. But our God is a different kind of king. The Psalmist says "he is robed in majesty." God isn't robed with fine fabrics, or any of the other symbols of worldly wealth; those are the way we cloth our own rules. God is clothed "in majesty." And when the Psalmist thinks of majesty, he thinks of roaring waters and pounding waves.
The imagery is meant to be startling and powerful, but it's also meant to be comforting. We are ruled by a God who oversees all that is. God controls all, cares for all, and comforts all. That is a God who is worthy of worship. That's a kind that is worth singing songs of praise about. That's a God worth bowing to.
