The scribes from Jerusalem had called Him Beelzebub, which means satan. Jesus wanted them to know that no kingdom will fight against its own people and an outsider can not enter into a strong man's house to rob and get away with it freely. Obviously the strongman will repel the robbery unless you tie him first then you can succeed in robbing his house. Jesus was only exercising His authority over demons and the scribes did not understand His authority.

Jesus' words makes me feel free from all evil.

Jesus's words makes me feel saved,loved by God and all people. With Jesus' words i feel confident.
