In America's cities, God has brought the mission field to us!

I don't think the question of whether we should evangelize those of other religions is as good a question as, "Should we evangelize those who have already heard and don't want it?" Millions of animists in India and South America have been saved. We should be evangelizing other religions. However, there are enough fertile fields of people who have not heard/understood Christianity, that it may not be the best use of our energy beating a dead horse on those just not interested. If you have a fertile field and a rocky field, where do you sow your crops?
