Great and Holy Monday

Behold! The bridegroom cometh at midnight, and blessed is he whom He shall find watching; but unworthy is he whom He shall find heedless.  Beware, therefore, O my soul.  Do not be weighed down with sleep, lest you be given up to death and shut out from the kingdom.  But rouse thyself, crying: "Holy, holy, holy art Thou, O God!" Through the intercessions of the Theotokos have mercy on us!
