"For what is more consonant with faith than to recognize that we are naked of all virtue, in order to be clothed by God? That we are empty of all good, to be filled by him? That we are slaves of sin, to be freed by him? Blind, to be illumined by him? Lame, to be made straight by him? Weak, to be sustained by him? To take away from us all occasion for glorying, that he alone may stand forth gloriously and we glory in him?"
John Calvin, Institutes of the Christian Religion
