Since he will still have access to the Heavenlies, will Satan be watching the Bride receive our Bema Seat rewards? I can’t imagine that such an incredible event would be tainted by allowing him to be there.
Satan won’t be totally expelled from Heaven until the beginning of the Great Tribulation by which time the Church will have been there for several years. Therefore I suppose it’s theoretically possible that he could witness the bema seat judgment. Personally, I think the only way the Lord would permit that would be to give him a first hand demonstration of the magnitude of his defeat. But that’s just an opinion. There’s no Scripture to back me up.
