The Son of God did not want to be seen and found in heaven. Therefore he descended from heaven into this humility and came to us in our flesh, laid himself into the womb of his mother and into the manger and went on to the cross. This was the ladder that he placed on earth so that we might ascend to God on it. This is the way you must take. If you depart from this way and try to speculate about the glory of the Divine Majesty—without this ladder—you will invent marvelous matters that transcend your horizon, but you will do so at very great harm to yourself.

—Martin Luther
