Behold, the Bridegroom cometh at midnight, and blessed is the servant whom he shall find awake. But he whom he shall find neglectful is verily unworthy. Behold, therefore, my soul, beware, lest thou fallest into deep slumber, and the door of the kingdom be closed against thee, and thou be delivered to death. But be thou wakeful, crying Holy! Holy! Holy! art Thou, O God. . . .
I behold Thy bridal chamber richly adorned, O my Saviour; but I have no wedding garment to worthily enter. Make radiant the garment of my soul, O Giver of Light, and save me. . . .
Come, ye believers, let us work diligently for the Master; for he distributes wealth unto his servants. Let each of us according to our ability, increase the gifts of grace twofold. (Tuesday) . . .
Rich men have turned poor and gone hungry; but they that seek the Lord shall not be deprived of any good things (Psalms 33 from Septuagint)
(from the Bridegroom Matins & the Pre-Sanctified Liturgies of Holy Monday, Tuesday, & Wednesday)
Let the brother in humble circumstances glory in his high position; and let the rich man glory in his humiliation, because like flowering grass he will pass away. (James 1:9-10)
O Bridegroom, brilliant in Thy beauty above all mankind, who didst call us to the spiritual banquet of Thy chamber, cast away from me the likeness of the rags of iniquity, by participation in Thy Passion and adorn me with the robe of Thy beauty, and distinguish me as a brilliant guest in Thy kingdom, for Thou only art compassionate. (Tuesday Matins, from the Aposticha)
