Jealousy is central to the fundamental essence of who God is. Jealousy is at the core of God’s identity as God. Jealousy is that defining characteristic or personality trait that makes God God. Whatever other reasons you may find in Scripture for worshiping and serving and loving God alone, and there are many of them and they are all good, paramount among them all is the fact that our God burns with jealousy for the undivided allegiance and affection of His people… At the very core of His being, in the center of His personality is an inextinguishable blaze of immeasurable love called jealousy.
