Smack Talk

I have found lately that I talk an awful lot.
I was at art night last night with some friends and some new friends, and afterward I realized that I had said a whole lot.
When I'm getting to know people, Christians specifically, I find that I speak in great lengths about grand things. Things that have happened in my life, Christian things specifically. I find I don't mind sharing my past, what I have gone through, the cool things I have done and stuff like that.
I also seem to have no problem spouting "Christian" wisdom, or the equivalent of what could pass as such, and at the very least, my opinion in the form of what's wrong with our world.
I have no problem "sounding" wise or pretending that I'm smarter than I actually am. I have no issue with being passionate about social ills of the world, the United States, and formulating solutions that would CLEARLY fix ALL the problems on the planet.

Why do I do that?
When all is said and done, do I really live up to my smack talk?
Or if you prefer "Christian-ease", do I "Walk The Talk?"
I'm not so sure. I know what I am in my head, I know the sins I still struggle with and I know the "BS" that I spout. Not that I do it on purpose, I fully believe the things that I say and what I am passionate about. But I wonder, is it just me, or does everyone feel the same way? Does everyone come off of a conversation feeling like they've just attempted to "BS" their way into heaven?

The Bible tells us at the end of time, that we will give an account for "EVERY idle word." We will have to explain to God everything we meant when we said what we said. How discomforting.
I understand why God speaks in a still small voice, and when I get so loud I run the risk of drowning Him out. Maybe I should be less concerned with sounding good and just let my actions scream.
