Then you are mistaken, and you know nothing about me, and nothing about the sort of love of which I am capable. Every atom of your flesh is as dear to me as my own: in pain and sickness it would still be dear. Your mind is my treasure, and if it were broken, it would be my treasure still: if you raved, my arms should confine you, and not a strait waistcoat–your grasp, even in fury, would have a charm for me: if you flew at me as wildly as that woman did this morning, I should receive you in an embrace, at least as fond as it would be restrictive. I should not shrink from you with disgust as I did from her: in your quiet moments you should have no watcher and no nurse but me; and I could hang over you with untiring tenderness, though you gave me no smile in return; and never weary of gazing into your eyes, though they had no longer a ray of recognition for me.”
― Charlotte Brontë, Jane Eyre
This is the kind of love God shows to us in sickness and in health.
