And the devil said to him, "If you are the Son of God, command this stone to become bread."

And Jesus answered him, "It is written, 'You shall worship the Lord your God, and him only shall you serve.'"

And no wonder, for even Satan disguises himself as an angel of light.

Are they not all ministering spirits, sent forth to serve for the sake of those who will inherit salvation?
