It is not Christianity that is just one way among many, but pluralism. Jesus Christ said he is the only way to God, the only way to heaven. But there are many paths to hell, and pluralism is just one of them. Can I leave you with something to think about. One of the things about pluralism in our society is that it intimidates us into silence.
Pluralism prides itself on religious tolerance.
But it is extraordinarily intolerant of anyone who has the gall to say that someone else's idea of God is wrong. If you believe the gospel, and let people know it, you will be accused of narrowmindness, bigotry, and all kinds of evils. You will be called fundamentalist, fanatic, uncharitable. But we must reclaim the right to stand up for absolute truth in the face of relativism. We must get used to talking about God in the very specific and exclusive way that passages like Deuteronomy 6 speak.
