“The Bible defines idolatry as the human tendency to elevate something in creation to the status of God. In Romans 1:25, the apostle Paul writes, “They exchanged the truth about God for a lie, and worshiped and served the creature rather than the Creator.” Humans are inherently religious, and when they deny the Creator, they will fasten on to something within creation and elevate it to an object of worship. In practical life, people who reject God will seek some substitute emotional fulfillment: power, profit, or pleasure. In intellectual life, they will seek some substitute to play the role of the divine in their thinking – the ultimate reality, the source of everything else. Worldviews are idols of the heart (Ezekiel 14:3).”
