Beliefs are not important. VALUES are important. (Values are what you hold as important, if you want to believe that there is purpose other than the values yourself you are free to do so)
In real-people speak: don't be a dick/love thy neighbour
The message of the bible or any other holy book is important, not the words it uses to convey that message. People all get tied up in the specifics. Look at the generalities, and ask "why?". God is within, not without. He is Plato's "good".
I am an atheist, I enjoy reading religious stories, stories designed to TEACH TRUTHS, not stories designed to be taken as FACTUAL TRUTH. I do not disrespect those who hold religious beliefs, because it is a thin line that separates me from them, that line is the line of the agnostic. I would say I'm a realist agnostic, I think that either god and the afterlife are poetic metaphors (and are to be taken as lessons, not facts), or there is a god and/or afterlife that could only barely resemble any image we could draw of it.
You can ask questions like "How can gay marriage ever be legal? (word of god/love)" you should ask "What is the purpose of marriage? What is primary, what is secondary? Are gay marriage and hetro marriage mutually exclusive? What are the social implications?".
Truth brings people together, lies divide us. Perceived truth has some truth in it (and some lies), Perceived lies have some lies in them (and some truth). There can be truth in a lie and lies in truth. Get over your bias, listen and be heard.
There are walls between us that we have built. I don't expect these walls to be broken in my lifetime but it pains me to see people drawing their lines in the sand nonetheless.
