Before you get sucked in to any of these quacks (my personal opinion ) get a sworn statement from a qualified medical Practioner that the person claiming to be healed has in fact the condition they claim they are being healed of.
If you cant verif that the "healed" person has the affliction in the first place , why would you believe them on face value ?
These people prey on the gullible and those who WANT TO BELIEVE.
Con artists thrive on the vulnerability of persons who are looking for quick answers to complex problems.
And Religion is a great money making racket enslaving the bulk of mankind around the world.
Christianity alone has over 40,000 different sects all claiming they have the truth.Think of all the contributions $$$$$$ that each of these sects bring in each week , with hundreds ,thousands and even millions of followers donating their money each week , and that is only Christendoms religions.
