How do we know the doctrine of God's jealousy is true?

The Bible reveals God as a jealous God in Exodus 20:5, emphasizing His demand for exclusive loyalty and worship. This jealousy is not akin to human envy; rather, it expresses God's protective nature regarding His glory. He will not share His position or honor with other gods, which indicates the seriousness of His covenant with His people. This doctrine is essential for understanding the nature of our relationship with God, as it underlines His holiness and the expectation that we worship Him alone. God's jealousy reflects His deep commitment to His people and His rightful position as sovereign over all creation.
