I most certainly am glad you hung around as I've learned quite a bit from you.I've spent a large portion of my life in internet discussion/debates. I started out in "yahoo chat" in the late 90s and I've been debating theology ever since. I've spent so many hours it is impossible for me to try to quantify it all. Outside of sleeping, working, and family life. It is the single largest thing I've done. I've questioned myself over and over again as to its value. I'll tell what I've come up with and leave it at that.
I can't be happy without talking about God. I can't. I believe there is a hole in every human being that can only be filled by Jesus Christ. When I "debate/write".... That is what I'm doing. I'm filling that hole with Him.
Ultimately, I find pleasure in it no matter how trying it might be at times. Everything is open to scrutiny. When we scrutinize one another... we make each other better.
Yes. There is plenty of fruitless debate taking place.... but you never know just how something little can make a HUGE difference somewhere. Even if it doesn't. Let our words always praise Him.
