What does the Bible say about following God versus false gods?

In 1 Kings 18:21, Elijah challenged the Israelites to determine whom they would serve, stating, 'How long halt ye between two opinions? If the Lord be God, follow Him. But if Baal, then follow him.' This question emphasizes the necessity of making a clear choice between true worship of the one true God and the allure of false idols. In a world filled with various beliefs, this passage serves as a reminder that there are fundamentally only two paths: works or grace, dependence on human effort versus dependence on divine sovereignty.
