The objects of worship may change over time, but the heart stays the same. What we do now is no different from what the Israelites did with the golden calf. When the Israelites left Egypt, they felt very vulnerable and needy (and were hard-hearted and rebellious). Even though they had witnessed the power of God, they felt afraid. They felt out of control. Their remedy was to choose an idol over the true God. By doing this they were both opposing God and avoiding him.
