I understand Satan and his angels are still in heaven, but how are they here, too? They torment us and Satan tried to tempt Christ on this earth. How can this be?
Satan and his angels can only be in one place at a time, but like all angels they are supernatural beings. That means they can travel between dimensions quickly, moving from heaven to earth and back almost instantaneously. Some scholars believe that after the rapture we will have that same ability.
