There are 3 heavenly realms, Satan/Lucifer and the 1/3 who were with him at his exit are there. That realm is between earth and Gods realm. So, yes, there is evil in a heavenly realm. Something to note… God does not need and army of angelic hosts…. He disbursed Lucifer and the others. The Hosts are for mankind to use in the fight against the unseen evil that is here. We fight the spiritual forces, using spiritual forces. Have you learned how to do this…. it is the force I use in watching over this board.
