Where Did All The Churches Come From?: Does It Make Any Difference To Which I Belong?

Did you ever wonder why there are so many religions in the world? There are perhaps hundreds that do not even worship Jehovah. (That is really another story,) And why do we have so many churches now? They teach different doctrines; they worship and work in vastly different ways; they all aim for Heaven in so many different ways. They may all be wrong, in spite of their sincere good intentions, their love of God and their desire to please Him, but they cannot all be right. Does it make any difference to which I belong?
