God and God alone is the final, ultimate goal of our quest. All that God is for us in Jesus is the Object of our quest for joy. When I speak of fighting for joy, I mean joy in God, not joy without reference to God. When I speak of longing for happiness, I mean happiness in all that God is for us in Jeuss, not happiness as physical or psychological experience apart from God. Whether we are desiring or delighting, the end of the experience is God.
