Few years ago a co who is in Bethel now told me that almost all growth in the UK Is because of immigrants, mainly from Poland.
My experience is: Brits don't go to ministry on evenings when people are in. Saturday mornings are mostly not at homes and only an hour. And then coffee stop. No wonder no new converts, youths bored and all discouraged.
Immigrants are far more industrious . I keep seeing polish and Slovak jaws in my area at nigh time doing d2d. They preach as they work - hard. I apologise Brits but they have more power. Besides, they as newcomers create sort of support groups.. and they need it.
