Recently, while recovering from a brief period of being under the weather, I let my wife drive on a trip to her sister's house. Like most men, I prefer to steer when we travel together. It has nothing to do with my wife. She is an excellent driver (although I think I could beat her on the racetrack). It's a guy thing.
My rare turn as passenger was a pleasant experience as I viewed the world from the other side of our van. I saw new houses that had been built, animals in fields, a half sunken boat pulled alongside the shore, piles of interesting junk in yards, students playing hooky on the golf course, and much more. All of those things are there when I drive, but being in control limits what I can see. Not being in the driver's seat gives one a whole new perspective on the great, big, world we live in.
The same is true in our walk with Christ. Many Christians suspect that there are great and wonderful things out there that God has for them. However, instead of giving control of their lives over to God, so He can lead them to where His full plan for their life can be experienced, some Christians insist on staying in the driver's seat. It's a sin thing. They may claim to want God's will for their life, but they reject His control over it. It's the difference between full surrender and a calculated retreat.
There are some things that we will never see until God is in our driver's seat.
