To say that God is jealous certainly does not mean that He is suspicious because of some insecurity in His heart. This kind of jealousy is the result of ignorance and mistrust. Such is surely not true of our all-knowing God. Nor does it mean He is wrongfully envious of the success of others. Jealousy that is sinful is most often the product of anxiety and bitterness and fear. But surely none of this could be true of our all-powerful Creator – God. Sinful jealousy is the sort that longs to possess and control what does not properly belong to oneself; it is demanding and cares little for the supposed object of its love.
