My son is born again and he says anyone that isn't born again will not go to heaven. How can this be? I was baptized a Christian in an Episcopalian church. What about Catholics? He drives me nuts with his know-it-all attitude on the Bible. I have a gay brother and he is the most wonderful person in the world and he is also Christian as he was also baptized and believes in God. "Born agains" can be very frustrating people!
The surest way to not be bothered by fanatical individuals -- of any faith -- is to learn, for ourselves, the truth of these things. Millions believe they are reborn, but are really just living bores who are scared of everything that threatens their delicate (and highly conditioned) psyche. Just do your own inner work, ask the Light (of Christ) to lead you to His supernatural Home, and you won't be troubled anymore by temperaments such as the one you have described. Why? Because in your awakening to your True Self, in Christ, you will have already transcended their little lives.
