God repeatedly uses his people not to glorify themselves or to give some advantage to others, but to glorify God. “God has given us the joy of spiritual sight so that we might spread the reputation of our eye doctor. Or you could say that we were caught in a deep mine shaft and it was caving in on us, and Jesus came down into the collapsing shaft of our sin and guilt and fear, and he put us on his back, and at the cost of his own life got us out. Why? So that we would spread the reputation of his courage and strength and kindness”.
