I still remember my childhood picture Bible, (click here) which showed a shiny golden calf with people bowing down before it—a colorful depiction of the idolatry into which the ancient Israelites fell after Moses led them out of Egypt (Ex. 32). The story struck me as incredibly strange for two reasons. First, I wondered why anyone would be so ridiculous as to worship a golden calf. Obviously, the gold statue was not really a living god. Second, I wondered why God would care so much about what they did. They weren’t hurting anyone (were they?). It may be silly to worship a calf of gold, but why would God be concerned?...
