The Jihad has gone on for 1400 years and will continue until all living human beings are Moslem or until none are. If the former then it will continue as a sort of civil war as the different identities of Moslems slaughter each other seeking purity of Islam until either there is only one Molsem/human being alive, or until the population depletion of Moslem culture unable to raid and conquer and the technological retrogression leave the world’s remaining population in disconnected pockets.
Trouble is, even an evil jihad needs the virtue of unity in order to be able to carry on a coherent conquest.
The bible several times talks about dividing the enemy.
The devil is handicapped by his own selfishness.
Sometimes in this context I think about how Jesus said Satan can’t cast out Satan, and this has to be looked at from the right viewpoint to make sense. Sometimes Satan A can kick out Satan B. But from a godly point of view we are still left with Satan. A healing would take the forceful entrance of God.
