11 “That they may make known to the sons of men Your power, and the glory of the greatness of the beauty of Your kingdom”. Your saints then commend “the glory of the greatness of the beauty of Your kingdom,” the glory of the greatness of its beauty. There is a certain “greatness of the beauty of Your kingdom:” that is, Your kingdom has beauty, and great beauty. Since whatever has beauty, has beauty from You, how great beauty has Your whole kingdom! Let not the kingdom frighten us: it has beauty also, wherewith to delight us.
For what is that beauty, which the saints shall hereafter enjoy, to whom it shall be said, “Come, you blessed of My Father, enjoy the kingdom”? Whence shall they come? Whither shall they come? Behold, brethren, and, if you can, as far as you can, think of the beauty of that kingdom which is to come; whence our prayer says, “Your kingdom come.” For that kingdom we desire may come, that kingdom the saints proclaim to be coming. Observe this world: it is beautiful. How beautiful are earth, sea, air, heavens, stars.
Do not all these frighten him who considers them? Is not the beauty of them so conspicuous, that it seems as though nothing more beautiful could be found? And here, in this beauty, in this fairness almost unspeakable, here worm and mice and all creeping things of the earth live with you, they live with you in all this beauty. How great is the beauty of that kingdom where none but angels live with You! There is a greatness of a certain beauty; let it be loved before it is seen, that when it is seen, it may be retained.
