So, this church is using the pain and grief of others as a fundraising gimmick. Shame.
I followed Mark Marks, who runs a "healing ministry" whose primary "miracle" seems to be the leg-lengthing trick. When challenged on the effect of his particular prayers, the answer is: "So, you don't believe God can heal?"
I was a member of a healing church for years. I took what they had to say with a grain of salt, because I did believe that Holy Spirit was working, often in spite of the leadership. Finally I realized I would need a whole salt mine to buy what they were selling.
