Theophylact of Bulgaria
"The face of being" means knowledge of oneself through the law. Therefore the Apostle added the word "being" to the word "face."
Through the law we learn what we were when we came into the world. We also understand into what state the spiritual law regenerates us through the washing of regeneration.
Then, when we do not remain in such contemplation through activity, we forget the spiritual gift we have received. For whoever gives himself to evil works does not remember how he has been benefitted by God.
If he remembered that he had been born from above, justified, and numbered among the sons of God, he would not give himself to works that reject the grace granted to him.

From the ordinary mirror the Apostle turns his discourse to the noetic mirror, without drawing anything out from the example he presented in brief words.
He ought to have said this: "Whoever hears the law and does not fulfill it is like a man considering his face in a mirror.
Just as that man looked at himself, went away, and at once forgot what he was like, so also this man saw from the law of Moses why he was created.
He saw that he was created for the glory of God and for life according to the image of the God who created him. Yet he fulfilled nothing of what he saw.
He acted exactly like the man who looked in the mirror. He ought to have made use of what he saw, but, like that man, he did not make use of it."
The Apostle does not act in this way without purpose, in leaving something unspoken. He concentrates the listener and makes him listen with attention, not in passing.
For blessed are not such hearers, but those who join work to hearing. The Pharisees also were hearers. Yet because they were not doers, they were not blessed.
"Deceiving yourselves" means deceiving themselves, and counting their own salvation as nothing.
