Here's a quote to think on.
If you would be a real seeker after truth, it is necessary that at least once in your life you doubt, as far as possible, all things.
- Rene Descartes
Man, if that's not the truth.
It seems you never really "know" something until you've turned it upside down and inside out. It's true of the people in your life too. Until you take the time and effort to know them deeply and honestly, you're just guessing.
I think it's this idea of examining a thing to see if it is truth helps you to understand the things you say you believe.
This is often my general stance on all things "religious" or what someone is proclaiming to be "Biblical". There is great value in seeking something out for yourself.
There is no harm in reading the Bible to see exactly what it says. To a non-believer, I'd say no harm will come to you simply because you read the book. Equip yourself to know exactly what you're railing against. But the same holds true for the believer. Read the thing so you know exactly what you're defending or declaring.
As self-labeled Christians we often spend lots of time, energy and dollars soaking ourselves in all kinds of things that claim to be Biblical or Christian, yet we've never read the Bible for ourselves. We memorize all sorts of verses, yet we've never read them in the context they were intended.
Don't even get me started on religion vs. Christian.
It isn't about what we say, at least that's not the main part, it's about how we live, what we do and how we love.
