The Williams sisters are hypocrites.
They talk the talk and appear to 'praise' Jehovah, but their life is what the WT condemns on a regular basis: they have given their life over to tennis.
And I think that is a great thing, they are great at what they do; they should be free to pursue what their passion is.
But don't praise the witnesses, and pretend to be one; the witness leadership condemns the type of life they live, and the average BAPTIZED witness would be DF'd within days if they appeared without clothes on a magazine cover.
