Packer reminds us that God’s jealousy is not like human envy but a holy, protective love that refuses to share His people with idols. He likens it to a husband’s rightful jealousy for his wife’s faithfulness. God’s jealousy flows from His deep commitment to us—He desires our whole-hearted love because He knows life is found only in Him. When we turn to false gods, His jealousy is aroused, not out of insecurity but out of covenantal love. This divine jealousy highlights both His justice and mercy, drawing us back to fidelity, worship, and the security of belonging fully to Him. Without understanding this, we miss the heart of Christianity. Packer turns to the results of the atonement, showing that believers are not just forgiven but made children of God.
