For example, I think there are at least four possibilities of a cause of depression. One is physical, and that shows itself in several different ways, sometimes it's just exhaustion, it's just a lack of capacity, it's a post adrenalin reaction. In other words if you run a marathon your body is going to react to that afterwards so is your emotions afterwards when you're spent.
There's a wonderful story in 1 Kings 18-19 chapter, it talks about Elijah, and some of you who're familiar with that story know that Elijah went up the 450 false prophets of Baal on Mount Carmel, and he challenged them to call down fire from the sky from their false god and they were unable to do so.
And he called down fire from the true and living God that consumed the sacrifice that was on the altar, and after that he and those who followed him killed the 450 false prophets of Baal. Well at that time the King of Israel was Ahab, a wicked king, he was married to Jezebel and Jezebel threatened his life.
Jezebel said, may it be done to me what you did to those prophets if I don't do to you what you did to those prophets by the end of this evening. So, the Bible tells us that after this great ordeal, after the spiritual Superbowl which he had to be spent following that he ran for an entire day into the wilderness, not a really good idea.
He'd just seen God call down fire from the sky, his God was able to defeat Jezebel but because he was depleted he was afraid and then he expanded even more energy going into the wilderness. And sometimes that's what we are what we have is we have a down that takes place after the adrenalin has give us an artificial high and we have spent our energy, we've spent our emotions, we loose both our physical and our emotional margin, and we go into a natural reactive state and many of us worry about the way we feel, we feel exactly like we should feel after some of those experiences.
