Why so many Religions can they all be right

The lesson this last week started down a road of division. The lines are being drawn on differences in what they all believe.  The questions that were brought up were "Why so many religions... can they all be right. The way people believe they go to heaven came up and brought on some discussion. We looked at John 14:6 Jesus answered, "I am the way the truth and the life no one comes to the father except through me."
