Casting out devils is a warfare where the stronger
overcomes the weaker. Jesus said, the devil must
be bound before He is willing to come out. They
do not respect anything other than force.

Demons are spiritual beings. Physical force has no
power over them. Drugs may act on the nerves
they effect but not over the spirits themselves.

It is the action of God's spirit through faith that
can have victory over them. So Jesus said, "But if I
cast out devils by the Spirit of God, then the king-
dom of God is come unto you" Matthew 12:28
