As for you, however, if you do not trust the prophets, and if you suppose both the fire and the men who saw it to be a legend, the Lord Himself shall speak to you, He “who being in the form of God did not count equality with God as an opportunity for gain, but emptied Himself,” the God of compassion who is eager to save man. And the Word Himself now speaks to you plainly, putting to shame your unbelief, yes, I say, the Word of God speaks, having become man, in order such as you may learn from man how it is even possible for man to become a god.
