TB Joshua is my boy! - Witch doctor Kwaku Bonsam

Popular Ghanaian witch doctor, Priest Nana Kwaku Bonsam, has had a 'war' with popular Nigerian Prophet, TB Joshua,
 at least once in the last two years Priest Nana Kwaku Bonsam says he backs up over 1,700 African preachers 'spiritually.

He said,Prophet TB Joshua, the founder of Synagogue 
Church of All Nations (SCOAN), has come under fire 
several times for allegedly hiring people to pretend to be
 sick and disabled and then claim to heal them during
 his prayer meetings.

Kwaku Bonsam, who operates from a shrine at Sa-Peiman,
 a village on the outskirts of Nsawam in east Ghana, is assumed to be a very strong witch doctor who is also 
called 'Devil of Wednesday'.

Apparently, this Ghanaian "priest" is said to be very 
powerful, that he has claimed he is the 'spiritual father'
 of some of the most powerful preachers in Africa.

Here's what the "priest" had to say:

"Over 1,700 pastors and so called men of God from 
different parts of Africa have approached me, seeking 
powers to perform miracles, including Prophet T.B Joshua from Nigeria. He is my boy. I challenge him to come out 
and deny this.

"Apart from the pastors, many prominent business people 
and celebrated church founders in Africa frequent my 
shrine for my services and if they deny, I am going to 
name them."

The question is, why would he choose to threaten to 
expose his 'dedicated' patrons?
