Charles H. Spurgeon on Psalms 29:7

The voice of the Lord divideth the flames of fire. As when sparks fly from the anvil by blows of a ponderous hammer, so the lightning attends the thundering strokes of Jehovah. "At first heard solemn over the verge of heaven,

The tempest growls; but as it nearer comes,

And rolls its awful burden on the wind,

The lightnings flash a larger curve, and more

The noise astounds: till overhead a sheet

Of livid flame discloses wide; then shuts

And opens wider; shuts and opens still

Expansive, wrapping ether in a blaze."

The thunder seems to divide one flash from another, interposing its deepening roar between the flash which precedes it and the next. That the flashes are truly flames of fire is witnessed by their frequently falling upon houses, churches, etc., and wrapping them in a blaze. How easily could the Lord destroy his rebellious creatures with his hot thunderbolts! how gracious is the hand which spares such great offenders, when to crush them would be so easy! Flames of fire attend the voice of God in the gospel, illuminating and melting the hearts of men: by those he consumes our lusts and kindles in us a holy flame of ever aspiring love and holiness. Pentecost is a suggestive commentary upon this verse.
