In a context and culture where we generally don't go before a physical image or man-made object to worship, Pastor Mack addresses what idols look like in our day, and how we can avoid constructing idols in our lives.
We are to have no other gods besides the LORD, but we need to know this God that we serve. If we do not, we run the risk of misidentifying Him, and thus, worshiping someone or something that is not Him at all.
