The one thing that angels and saints, as we are described in Scripture, have in common is that we are servants. We exist and are called by God to be servants. You will know that that’s what angels were created for. This is the real horror of what happened to Satan. He was created an angel by God; he became a fallen angel because he rebelled against his status and fell. Isaiah cries,“How you are fallen, Lucifer, son of the morning.” And he fell from the high glory of his privilege of being created as a servant to glorify God.
