How Can I Know I Am Saved

What is going on in churches and in the Christian faith today? What
exactly do we believe and why? Can Christians articulate their
beliefs and does it really matter? So what if a person prays a
prescribed prayer? Anyone can do that! What are the fundamentals of
the faith? To be a right-wing Republican? To be a theological
conservative? To be a "Reformed Christian"? Does it really matter
what we specifically believe if we already have the "basics"? Why
bother with the minutia of theology if all we really need is simple
faith? Is it true that a person who simply "prays the prayer" and
"lives the life" is saved? Saved from what? Saved from hell? A
conscious hell? Really? Do Christians truly believe that all people
who don't "believe the way we do" are going to suffer eternal and
conscious punishment? If we believe that, why are we not out
pleading with our friends and relatives to "come to know the Lord"?
