It is only when I’m hooking my life to the glory and grace of God and getting my identity from him that I can truly live with singleness of focus for the long run. This is because it is only God who has the power to satisfy my heart. I was made for him. I was made to have my life shaped by an acknowledgment of his presence, a rest in his love, and an active allegiance to his purposes. When I live this way, my soul is satisfied and my heart is at rest.
