The devil was cast out of heaven, but listen to what the Bible says about that,
“Therefore rejoice, O heavens, and you who dwell in them! Woe to the inhabitants of the earth and the sea! For the devil has come down to you, having great wrath, because he knows that he has a short time” (Revelation 12:12).
Heaven is a better place with the devil gone, but earth is a worse place with him here, where we live!
What can we do about that? We cannot kick him off the earth, but we do know that he is filled with wrath against the people of God, and he will attack us relentlessly since he knows that he only has a short time before God casts him into hell.
Therefore, be aware that the devil will use whatever he has to bring you down with him. Do not give in, and do not give up, but wash yourself in the blood of the Lamb, hold to the word of God, and love not your death to the death (Revelation 12:11).
