In his sermon, John Ortberg compares submission to Jesus to driving a car:

When it was time to take our first child home from the hospital, we put her in the car seat in the back of the car, and then I got in the front seat to drive. She was so small even the baby seat was way too big. She looked so fragile to me that I drove home on the freeway going 35 miles per hour with the hazard lights flashing the whole time.

That first day, when your kid is in the car with you, is a scary day. Does anybody want to know what the next really scary day is with your kid in the car? It's when they turn 16, and now you're handing over the keys. Now they're moving from the passenger seat, from the ride-along seat, into the driver's seat. That's a scary moment.

It is a big moment in your life when you hand someone else the keys. Up until now, I've been driving. I choose the destination. I choose the route. I choose the speed. You're in the drive-along seat. But if we are to change seats, if you're going to drive, I have to trust you. It's all about control. Whoever is in this seat is the person in control.

A lot of people find Jesus handy to have in the car as long as he's in the ride-along seat, because something may come up where they require his services. Jesus, I have a health problem, and I need some help…. I want you in the car, but I'm not so sure I want you driving. If Jesus is driving, I'm not in charge of my life anymore. If he's driving, I'm not in charge of my wallet anymore. If I put him in control then it's no longer a matter of giving some money now and then when I'm feeling generous or when more of it is coming into my life. Now, it's his wallet. It's scary. If Jesus is driving, I'm not in charge of my ego anymore. I no longer have the right to satisfy every self-centered ambition. No, it's his agenda. It's his life. Now, I'm not in charge of my mouth anymore. I don't get to gossip, flatter, cajole, deceive, rage, intimidate, manipulate, exaggerate. I get out of the driver's seat and hand the keys over to him. I'm fully engaged. In fact, I'm more alive than I've ever been before, but it's not my life anymore. It's his life.
