Exodus 34:8-14: in context

As God renews his covenant with Israel, he warns them against making alliances with the peoples of the land and their gods, and he gives a reason rooted in his own character. You shall worship no other god, he says, for the LORD, whose name is Jealous, is a jealous God. God names himself Jealous; his jealousy is not incidental but part of who he is. He will not share the devotion of his people with other gods, but claims their whole worship for himself, because he is a jealous God.

God's jealousy can sound strange to us, for we often think of jealousy as a petty or insecure vice. But God's jealousy is not that; it is the jealousy of committed love. A faithful spouse is rightly jealous for the exclusive love of the one they are bound to, and would be wronged if that love were given to another. Such jealousy is not a fault but the proper response of love to unfaithfulness; it would be a defect of love not to care. God's jealousy is like this: he loves his people with a committed, covenant love, and he rightly will not share their devotion with rivals, for to give their worship to false gods is a kind of unfaithfulness to the God who loves them. His jealousy is the jealousy of love that desires the whole heart of the beloved. This reframes God's claim on our exclusive devotion. God's demand that we worship him alone, giving him our whole hearts, is not the demand of an insecure tyrant but the desire of committed love. He wants our whole devotion because he loves us and has bound himself to us, and he will not be content to share our hearts with rivals, the idols and loves that would draw us away. I am jealous for you, Paul says to the Corinthians, with a godly jealousy, desiring to present them as a pure bride to Christ. God's jealousy is love's jealousy for the faithfulness of the beloved. This searches whether we give God the exclusive devotion his love desires. God is jealous for our whole heart; he will not share our devotion with rivals. And the question is whether we give him that whole devotion, or divide our hearts, giving him a portion while our deeper loves go to other things, the idols of our own age. You shall love the LORD your God, the great commandment says, with all your heart. God's jealousy is the jealousy of a love that desires all of us. And rightly understood, it is not a threat but a wonder: that God cares enough for us, loves us enough, to be jealous for our devotion, unwilling to share our hearts with what would harm us. This calls us to give God the whole-hearted, exclusive devotion that his jealous love desires, not dividing our hearts with rivals, but loving him with all we are, as the beloved of a God who is jealous for us with the jealousy of committed love.

Do I misunderstand God's jealousy as a petty demand, or divide my heart, giving God a portion while my deeper devotion goes to other things, and can the truth that God, whose name is Jealous, is jealous for my devotion with the jealousy of committed love, like a faithful spouse jealous for the beloved's whole heart, move me to give him the exclusive, whole-hearted devotion his love desires, loving him with all I am rather than sharing my heart with rivals?
