As someone who has been around for a while I begin to wonder about why things are the way that they are. And then I realize that we live life according to the laws and rules that God set in place in creation. We interact with people and with the natural world according to the way God set it all up.
We start out in life living lives full of wonder and having basic needs. We need food and we need to be changed. But on the other hand everything is new and exciting and full of wonder. Everything is interesting. This is the natural order of things.
We start out in the Christian life in much the same way. We are born again into a brand new life. Everything in the faith is interesting and exciting and full of wonder. Everything is for everyone.
Churches that experience revival go through a similar process. Everything if fresh and exciting and interesting. Every experience is new. Every decision is full of wonder. Every event is astonishing.
But, as we grow up and as we grow older, things change. It does not happen overnight. Rather, it is a gradual fade. We have been down this path before and we have read this story before and we have wrestled with these decisions before and resolved them. And we reach a point when we feel foolish acting like we are young still. We think that we still can, but we can't.
It is not that God has changed or that revival is over. It is that we have changed and that it is rare to be moved with awe and wonder anymore. This is how God created life to be lived for people and for churches. This is why life is about enduring to the end, not being giddy over thing we have see before.
This is why we must keep planting churches. The exciting times are always when things are brand new. This is why the thrust of revival is not in the old churches who pay for it, but in the pioneer churches where new converts are still full of zeal and excitement. Out where everything is interesting and full of wonder.
New converts in an older church are like grandchildren. All of the excitement of being young, except that you cannot give them back to their parents when you get tired of them!
