Venus Williams is a high profile tennis player who claims to be a Jehovah`s witness as i think is her sister Venus Williams ,and i havent heard the JW religion/GB ever saying anything different ?
That`s in the USA
In Australia ,professional footballer in the AFL , bearded Alec Rance claims to be a Jehovah`s Witness and again i havent heard the JW religion/Gb saying anything different .
Note: Neither of them to my knowledge have ever been baptized so that could be there get out of jail card.
Note : You don`t get to these standards of optimization in your sporting field unless you put in the hard yards of dedication and commitment and years and years of sweat and tears.
That is not something the Jehovah`s Witness religion want`s you to spend your time effort and money on.
