Turning this thing around

I feel like I'm hunched over a huge steering wheel, using all my arm and back strength to crank the wheel desperately to the left so that I can change my semi truck's momentum and start heading a different direction. It's exhausting, the effort may fail (can you say crash, rollover, destruction?) and I'm not even sure what the new direction is. But I'm committed to the change and I pray that God will strengthen me to keep cranking on the wheel - or maybe even take over the whole thing. After all, what's the point of having a savior if I don't let myself get saved?
