The God Who Is Delightful and Dreadful
An act of holy heroism? No! It was an act of arrogance, a sin of presumption. Uzzah assumed that his hand was less polluted than the earth. But it wasn't the ground or the mud that would desecrate the ark; it was the touch of man. The earth is an obedient creature. It does what God tells it to do. It brings forth its yield in its season. It obeys the laws of nature that God has established. When the temperature falls to a certain point, the ground freezes. When water is added to the dust, it becomes mud, just as God designed it. The ground doesn't commit cosmic treason.
