Basil of Caesarea

When the day's work is ended, thanksgiving should be offered for what has been granted us or for what we have done rightly therein and confession made of our omissions, whether voluntary or involuntary, or of a secret fault, if we chance to have committed any in words or deeds, or in the heart itself; for by prayer we propitiate God for all our misdemeanors. The examination of our past actions is a great help toward not falling into like faults again; wherefore the psalmist says, "The things you say in your ears, be sorry for them on your beds."
