Luther talked often about the “Hidden God.” He was intrigued by God’s chosen vehicle of self-revelation. God always chose to show up in the most unexpected places, the settings where man would never look for Him.
He suggested that where God does not show Himself is just as important to understand as where He does reveal Himself. Listen to this thought provoking quote by Luther.
We have to argue in one way about God or the will of God as preached, revealed, offered, and worshiped, and in another way about God as he is not preached, not revealed, not offered, not worshiped. To the extent, therefore, that God hides himself and wills to be unknown to us, it is no business of ours.
We must understand where God is not preached. God chooses the sermon. He chooses the location of his self-disclosure. In other places he is clear, the cross and resurrection is the locus of God’s unveiling. He is preached there! Anywhere else, we must recognize there is no divine sermon—you won’t hear of him if you don’t tune in at Calvary.
