As thought comes before speech, so the remembrance of death and sin comes before weeping and mourning...To be reminded of death each day is to die each day; to remember one's departure from life is to provoke tears by the hour...Just as bread is the most necessary of all foods, so the thought of death is the most essential of all works. The remembrance of death brings labors and meditations, or rather, the sweetness of dishonor to those living in community...Just as some declare that the abyss is infinite, for they call it the bottomless pit, so the thought of death is limitless and brings with it chastity and activity.
Someone has said that you cannot pass a day devoutly unless you think of it as your last.
Remembering that humanity must still die keeps our sins in the forefront of our mind standing in judgment of our behavior now so that they will not stand so before the Lord in the last days. Considering our own deaths also reminds us of the inadequacy of them when compared to the atoning death of Christ, for "the day is not long enough to allow you to repay in full its debts to the Lord."
