Can Satan leave hell and wander on the earth at will?
There is no Scripture that says or even hints that Satan was ever in hell or ever will be. At the present time he is just where he has always been from the time of his creation. Some day he will be cast down from that position in heaven to the earth with no power to ascend to heaven again. Hell is for those who are made of the dust of the earth. Satan is not such a creature.
