They at once recognised that that was the glory of God reflected from him; and just as it is almost as difficult for us to look at the sun reflected from a mirror as to look directly at the sun, so these men felt it almost as difficult to look straight at the face of Moses as to look straight at the face of God. But Moses was a wise man, and he showed his wisdom in this instance as well as elsewhere. He knew that that glory was only on the skin of his face, and that of course it would pass away. It was a superficial shining. And accordingly he put a veil over his face, that the children of Israel might not see it dying out from minute to minute and from hour to hour, because he knew these Israelites thoroughly, and he knew that when they saw the glory dying out they would say, "God has forsaken Moses. We need not attend to him any more. His authority is gone, and the glory of God's presence has passed from him." So Moses wore the veil that they might not see the glory dying out. But whenever he was called back to the presence of God he took off the veil and received a new access of glory on his face, and thus went "from glory to glory." "That," says Paul, "is precisely the process through which we Christian men become like Christ." We go back to the presence of Christ with unveiled face; and as often as we stand in His presence, as often as we deal in our spirit with the living Christ, so often do we take on a little of His glory. The glory of Christ is His character; and as often as we stand before Christ, and think of Him, and realise what He was, our heart goes out and reflects some of His character. And that reflection, that glory, is not any longer merely on the skin of the face; as Paul wishes us to recognise, it is a spiritual glory, it is wrought by the spirit of Christ upon our spirit, and it is we ourselves that are changed from glory to glory into the very image of the Lord.
