As far as missionary work of Christian organisation is concerened, this is not out of love for deprived class. it is all political. I happened to be in Africa. Missionary worked there till they could convert Africans. Now they ran away because there is no scope for conversion!
Hindu organisations are also doing service but it is not highlighted by English educated/ convent educated media. Go to chitrakut and see what Mr Deshmukh has done for poor villagers
