God's greatness lies in forgiving, in showing mercy, and in this greatness He is greater than the heart which condemns itself. Behold, this is that greatness of God which we have to speak of especially within the sanctuary; for here we know God differently, more closely – from the other side, if one may say so – that out there, where doubtless He is revealed, is to be known in His works, whereas here He is to be known as He has revealed Himself, as He would be known by Christians. The tokens of God's greatness can be known in nature everyone can behold with wonder, or rather there is no special token, for the works themselves are the tokens; thus every one can see the rainbow and must wonder when he sees it. But the token of God's greatness in showing mercy exists only for faith; this token is in fact the Sacrament. God's greatness in nature is manifest, but God's greatness in showing mercy is a secret which has to be believed.
