IT'S MONEY-MONEY & MONEY. India is a country of poors where people do not have place for shelter, clothes to cover themselves and food to fill their stomach. Thats where Xians come into picture and brainwash these poor people and pay some few pennies which last longs for a month or 2 or max an year after that these poor people are again on streets but the difference is, they are "Christians" now. If these Xians really have to help them then why to convert them to christianity ??
So, my dear friend, it's money which plays a major role in conversions, on which Xians are also enjoying their living, hope this is clear now.
