The Bible witnesses the existence of demons, which are hostile and powerful spirits to God and His church; that the devil is their principal chief to whom God created hell. The church who believe in Jesus as their Lord and Son of the Living God will not be destroyed by the devil. Christ assured that when He come back, He will throw to the hell all the bad angels and all who haven´t accepted Him as savior.
