We have several of them here in southeastern CT. I can't help but think that perhaps considering the abysmal state of Christianity in the UK, they could have stayed home and fought for Christ in their own country.
I have heard many of them preach and they all seem to have a whiff of anti-Americanism in their messages that might be a leftover from the usual snooty European mindset.
Os Guinness is another one who abandoned the UK for America. Every time I hear him he gives the back of the hand to America as if he just can't help himself. He's making a great living here. I've stopped listening to him. Too bad. His message is generally insightful and challenging but the anti-American remarks have driven me away.
I never even thought about it from that slant. Interesting.
