Worship is a storm front; lead from the lightning
Dark skies are the perfect canvas for one of the most powerful meteorological phenomena we know – lightning. And the majesty of lightning occurs when something unseen, but no less powerful, is at work behind the scenes. The same is true in worship.

Clouds and thick darkness surround him; righteousness and justice are the foundation of his throne. Fire goes before him and consumes his foes on every side. His lightning lights up the world; the earth sees and trembles.
Psalm 97:2-4 (NIV)
We’ve all seen it in a dark, stormy sky, and no matter how many times it makes an appearance, every one of us is filled with some degree of amazement. It’s a creative flash never appearing the same way twice, a discharge of potent electrical force. And it can crack a tree, strike fire to a building, or simply appear like Grace, as a spectacle for the dazzled eye.
It is lightning, and lighting is the result of something unseen happening that leads to its appearance. A meteorological phenomena happens when two masses of air, of different densities and temperatures, come crashing into one another. The result is a sign, a wonder, a physical glimpse of what is going on in the atmosphere.
