We have all been given authority to do this. All we have to do is become obedient vessels. Cut out the sin from your own life then invite the Holy Spirit into you. Then you will be an obedient vessel for God and do his work according to his will:
Luke 10:19 King James Version (KJV)
19 Behold, I give unto you power to tread on serpents and scorpions, and over all the power of the enemy: and nothing shall by any means hurt you.
Honestly, it’s fun to blast out demons and set people free. All it takes is for us to submit our wills to God and to do his purpose.
