If those who are asleep and who are drunk at night are reproached then how much greater is the judgement and reproach of those who are asleep during the day.
I mean, if those who sin lie in their hardness of heart, not knowing God or His laws, are like judged, then how much greater is the judgement and reproach of those who will sin after they have received all knowledge and that there is no God but Jesus.
[Abba Shenoute of Atripe, De Discrimine Temporum]
Brethren, if we want to escape God’s punishment and find mercy in his eyes, let us sit every evening alone by ourselves and search our souls for what we presented to our guardian angel to offer before the Lord. Again, as the night goes by and a new day dawns and light prevails, let us search ourselves to know what we presented to our companion angel to offer to the Lord.
Let it be beyond doubt that everyone of us – male or female- young or old, who was baptized in the name of the Father, the Son and the Holy Spirit has been assigned to a designated angel until the day of his death to report to him everyday what his assigned individual has done by day or by night.
Not that God is unaware of what we have done. Heavens forbid. He is more knowledgeable about it. As it is written. the eyes of the Lord are watching all the time everywhere on those who commit evil and on those who do good. Rather the angels are servants installed by the Creator of the universe for those who will inherit salvation.
[Abba Shenoute the Archimandrite, First Hour of Monday of the Holy Pascha in the Coptic Orthodox Rite]
