Writing is dangerous, because it reveals the heart.
Matthew 12:33-34 says, "...Out of the abundance of the heart the mouth speaks..."
People think they know you through your writing, but they truly only know a part of you: the part you're willing to share. And sometimes that's the best part; sometimes it's the worst part. Sometimes it's your willingness to share that says more about you than anything you say. It reflects a desire to be known, and to know others. To relate to people. And to dethrone yourself from whatever pedestal people put you on. In the worst case scenario, it creates a pedestal, which would swiftly be removed upon the meeting of the writer. Because you would realize we're not so different, you and me. I just write about my thoughts. You carry yours inside. And really, that's the beauty of it.
