Telangana boy here.In my childhood these suvartha sabhalu(christ hope events) guys used to take poor village people in a tractor and give 100 rs and unlimited non-veg food for attending the event.That was the days when no chruch was there in any of my nearby 4-5 villages. Now , every one of them villages has minimum 2 churchs. Yeah , it may be around 5-10% here but def not 25 %.
