What religion should you be in?
I think you can follow any religion because every religion
teaches good values and lessons which are really helpful in life.
According to me humanity is the best religion.
Think about your own morals and what you already know
instinctively to be right and wrong, research a mob of religions
(what they are meant to do, not what they actually do), and you
tell me the only one which doesn't go against what you already know
to be right.
If your question is what religion should you follow, then the
answer is simply the one that demonstrates and consistently
maintains truth, compassion, righteousness, respect and
unprejudiced appreciation for all of God's creation.
Another view: U said it, "be in" but not "be of"
