Luke 4:10

for it is written, 'He will put his angels in charge of you, to guard you;'

For he will put his angels in charge of you, to guard you in all your ways.

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

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

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

Are not they all serving spirits, sent out to do service for the sake of those who will inherit salvation?
