To love and admire anything outside yourself is to take one step away from utter spiritual ruin; though we shall not be well so long as we love and admire anything more than we love and admire God.

Context

“But it might, perhaps, mean that the person in question gives himself airs on the ground of his distinguished father, or because he belongs to a famous regiment. This would, clearly, be a fault; but even then, it would be better than being proud simply of himself. To love and admire anything outside yourself is to take one step away from utter spiritual ruin; though we shall not be well so long as we love and admire anything more than we love and admire God. (3) We must not think Pride is something God forbids because He is offended at it, or that Humility is something He demands as due to His own dignity—as if God Himself was proud. He is not in the least worried about His dignity.” source
