Within each of us exists the image of God, however disfigured and corrupted by sin it may presently be. God is able to recover this image through grace as we are conformed to Christ.
I will sing of the mercies of the LORD for ever: with my mouth will I make known thy faithfulness to all generations. For I have said, Mercy shall be built up for ever: thy faithfulness shalt thou establish in the very heavens.
The King James Version
I cannot believe that my illness is natural. I suspect Satan, and therefore I am the more inclined to take it lightly.
Martin Luther (laid low with a sudden illness)
