Then He was enveloped in a halo of glory.

If I could but impress upon you that glory is not a gift, but a consequence, a necessary consequence, of orderly and obedient development.

To the sight of angels, our beloved Lord Master was like every spirit of a child in His infancy, but there were no shadowy places in His development. 

In every temptation—and He was tempted in all points—He gained strength and energy, until in the fullness of time, He had so purified His human nature by constant victories as to permit of His receiving the Divine influx, needful for the manifestation of His miracles of healing. 

Then He was enveloped in a halo of glory.

Our Lord Master, growing always more glorious as He grew in power came to the Mount of Transfiguration, for it was necessary to show His chosen disciples His glory, lest the fearful scenes soon to begin should altogether overcome their faith. 

To angels, He was no other than as always seen, but the spiritual sight of Peter, James and John, who represented Faith, Love and Charity, was opened, and they beheld, not only Him in His glory, but Moses and Elias, and heard by spiritual hearing the end spoken of, as that which had been long since ordained.
