Luke 4:10

for it is written, He will give his agents orders about thee, to protect thee,

for he will give his [heavenly] agents charge over thee, to keep thee in all thy ways.

And the devil said to him, If thou are the Son of God, speak to this stone that it may become bread.

And having answered, Jesus said to him, Go thee behind me, Satan. It is written, Thou shall worship Lord thy God, and him only shall thou serve.

And no marvel, for even Satan disguises himself into an agent of light.

Are they not all ministering spirits sent forth for service for the sake of those who are going to inherit salvation?
