God’s own coming in glory is the real focus of Psalm 29 from start to finish, not the storm as a natural phenomenon. The temple, named explicitly in verse 9, provides the setting where that glory is finally seen and named. What the psalm describes is nothing less than God’s ascent and enthronement as sovereign King.
Psalm 29’s structure turns on its opening call, addressed to the ‘sons of the mighty,’ to give the Lord the glory due his name. ‘Glory’ here means something far more specific than vague praise: God’s own self-sufficient, omnipotent judgment displayed openly. The mighty Son that glory ultimately belongs to is Christ himself.
Spurgeon, Delitzsch, and Calvin all weigh in on Psalm 29’s thunderstorm imagery, each finding something different in it. Calvin’s own reading leans toward natural theology, God simply revealed through the storm itself. Van Til’s critique of that reading matters: general revelation alone, however powerful the thunder, cannot get us to the gospel.
