Don't be fooled into believing that those devils/unclean spirits in Jesus's day were a one time occurance, they have been just as rampant and busy in the lives of men since that time and up until now, if not more. Jesus also exposed them so that God's people wouldn't be ignorant of their activity, and Bible believers throughout the centuries have been protected from their influence because we have the indwelling Spirit and the instruction manual from God which warns us of them.

1 Timothy 4:1 Now the Spirit speaketh expressly, that in the latter times some shall depart from the faith, giving heed to seducing spirits, and doctrines of devils;

2 Corinthians 2:11 Lest Satan should get an advantage of us: for we are not ignorant of his devices.

Ephesians 6:11 Put on the whole armour of God, that ye may be able to stand against the wiles of the devil. 12 For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places.
