Prayer plays a vital role in such liberation. (Mark 9:25-29) But someone troubled by demons may need to take additional steps. Events involving first century Christians illustrate what else may be required.
Imagine...you pray to Jehovah the almighty for help......BUT....you might need ADDITIONAL help. Something ELSE may be required.
I guess even Jehovah needs an aid every once in awhile eh?
