I'm not assuming your brother, or anyone else, can't be good without religion. What I'm saying is that there's no evidence he or most anyone else would be better without religion, which is a pretty good paraphrase of your argument.
SEEK TO KNOW GOD not religion,satan loves "false religions" there are thousdands worldwide but there is only ONE TRUE GOD and your purpose in life is to seek to know GOD!!!
Yea, and one day maybe you'll realize christianity is just another one of them. It isn't any more believable than the other made up religions. Don't you think if you were born in Saudi Arabia instead of being a stupid chrstian you'd just be a dumb muslim?
