"When you close the doors to your dwelling and are alone you should know that there is present with you the angel whom God has appointed for each man...This angel, who is sleepless and cannot be deceived, is always present with you; he sees all things and is not hindered by darkness. You should know, too, that with him is God, who is in every place; for there is no place and nothing material in which God is not, since He is greater than all things and holds all men in His hand."

"God, being eternally good and bounteous, gave man power over good and evil. He made him the gift of spiritual knowledge, so that, through contemplating the world and what is in it, he might come to know Him who created all things for man's sake. But the impious are free to choose not to know. They are free to disbelieve, to make mistakes and to conceive ideas which are contrary to the truth. Such is the degree to which man has power over good and evil."
