We are told in Revelation the 12th chapter, the 9th verse that the Dragon is the devil, or Satan.



He appears as a 'sign' in heaven because at the time he appears, he is in the heavenlies.


..........[This is not the Third Heaven where the redeemed are].
.......Ephesians 6:12, in the literal translation, shows Satan and the powers of darkness dwelling in the heavenlies. They are soon to be cast down to earth. [verses 8,9]
