Watch therefore: for you know not what hour your Lord does come.

Watch therefore, &c. That Isaiah , "think continually that death is certain, but the day of death uncertain. I say the same of the Day of Judgment, both that particular judgment which comes to every one at death, as well as the general Judgment, which shall take place at the end of the world. Wherefore prepare yourselves for both by giving heed to virtue and good works." For as S. Jerome saith (in Joel c. ii.), "That which shall happen to all in the Day of Judgment is fulfilled in each at the day of death." And S. Augustine (Epist80) says, "In whatsoever state a man"s last day shall find him, in the same state shall the world"s last day come upon him; because as the man dies, so shall he be judged. Therefore ought every Christian to watch, lest the coming of the Lord find him unprepared. But that day shall find unprepared the man whom the last day of his life now shall seize unprepared."
Moreover, the reason why God wills that this day should be unknown to us Isaiah , that the uncertainty may be a never-failing stimulus to us in the practice of every virtue. "For," as S. Chrysostom says, "if men knew surely when they were to die, at that time only would they seek to repent."
The devil, therefore, in order that he may take away this stimulus of uncertainty, gets rid of it by degrees, and in part. He persuades every one that they have at least one year to live. When that has come to an end, he tells them they have another, and so on interminably. He causes men to believe themselves so strong and well, that they can surely live this one year. Year by year he does this, and puts such a thought into their minds as, "You are in very good health; you will not die this year." Thus it comes to pass that being, as it were, certain of life, they neglect repentance from year to year, deferring it to the year in which they are to die. Wherefore, when that year comes to each in which it is God"s decree that they shall die, they, in like manner, persuade themselves that they will not die in it. Thus it comes to pass that they are always unprepared when certain death and the last day overtake them. Wherefore this idea, instigated by the devil, must be crushed. Every one should say to himself at the beginning of each year, of each day, "It may be that thou shalt die this year or this day. Therefore so live as if thou wert to die to-day." This was the advice which S. Anthony was wont to give to his disciples, as S. Athanasius testifies, "When we awake out of sleep, let us be in doubt whether we shall see the evening. When we lay us down to rest, let us not be confident that we shall come to the light of another day. Thus we shall not offend, nor be carried away by vain desires. Neither shall we be angry, nor covet to lay up earthly treasures. But rather by the fear of departure, from day to day we shall trample upon all transitory things." Barlaam also taught the same to his Josaphat, "Think that this day thou hast begun the religious life. Think that this day also thou wilt finish it." S. Jerome says, "So live as though thou shouldst die today; so study as though thou wert to live always." The same Father ( Ephesians 16 , ad Principiam) says that Marcella was wont to praise that saying of Plato, "that philosophy was a meditation upon death;" and the precept of the Satirist, "Live mindful of death: time flies." She therefore so lived as though she always believed herself at the point of death. When she put on her clothes, she remembered the grave, offering herself to God as a reasonable, living, acceptable sacrifice.
