The last couple of nights have had some rough sleep. Tuesday, I remember waking up around 1AM and going to the computer, and very little else. The rest of the night, I dreamed of trainyards.
I've found myself growing more optimistic in general as I've gotten older. I've seen the predictions of the false End Times prophets ("this means we have to be in the last couple of years, because X is about to happen") fail to pan out. I lived through the end of Cold War and the Clinton Administration. God willing, I'll even survive GWB.
As I've told Number 1 Son, Iran isn't going to nuke Israel. The Bible says it won't happen. We aren't going to starve in the cold when oil runs out, because God said not to worry about food and water, that He would provide everything we need. And if He doesn't protect us from something, we still win by losing.
I'm not afraid of what comes up, even if what is coming up is bad. "Cheer up, the worst is yet to come!" And then He is coming.
