Matt 10:1 – And when He called unto him His twelve disciples , He gave them power against unclean spirits , to cast them out , and to heal all manner of sickness and all disease.

10:8 – Heal the sick , cleanse the lepers , and raise the dead , cast out devils : freely ye have  received, freely give.

As a covenant child of God, you have the power to heal the sick and cast out devil.
