I've even seen it level towns.
Oh yes, I believe in the wind, even though I've never seen it. For every effect, there is a cause.
In the same way, I have seen what the Lord can do, personally. I believe in Him, too...in fact, I fear him alot more than I do a Great Plains twister. You can't hide in your basement from Him forever.
It's the same when I look at history. His power and presence is evident to anyone who looks for it.
