Commentaries:
Making and worshipping an idol is foolishness and a lie, because a manmade image can never truthfully represent the Eternal God. For a son of God, worshipping idols is irrational (Acts 17:29); to look to something physical as important or more important than God defies all wisdom. The way the world looks to physical objects is superstition (e.g., good luck charms, religious crosses, shrines).
