All the angels, even the demonic nasty evil creatures (including Satan) work for Yahweh Sabaoth and they are ministering spirits, sent out to render service to those who will inherit salvation. They are servants to the children of God. And there is nothing those bad angels can do against a chosen one of God unless they first receive Yahweh Sabaoth’s permission to “minister” to a chosen one of God (in demonic terms, to come against them) and receive guarantee by Yahweh Sabaoth of their plan’s limitations and success.
