A blogging witness

I have often wondered if you could really use a blog to witness to someone. To share the gospel of God. It turns out that this may be more of a reality than I ever thought.
Today I was playing with a cheap quick thing that I threw up to catch my stats and stuff. To my surprise someone hit my site from typing into an msn search "what does God say about attitude". If you notice I am like the fourth link down there. How cool is that. It points to the main page of this site but is referring to an article I wrote on haunting scripture. Could it be that if I start writing about my travels down this God path that I would be fulfilling a calling from God to evangelize? I am not sure. But I am willing to start trying.
