Context is important...
Towards the end of his book Me, Myself, & Bob, Phil Vischer refers to the often-quoted passage Proverbs 29:18- "Where there is no vision, the people perish." None of the modern translations use the word vision, they use the word revelation. When the King James Version was translated, vision didn't mean what it means today. The context was totally different. It wasn't about goals and ambition and a "vision statement"...it literally meant a vision from God.
According to Paul, God had in mind even before I was born the "good work" he wanted me to do. I don't have to dream it up, I don't have to read a hundred business books and craft a "vision paper," I don't have to try a bunch of stuff and see what works. I just have to stop and listen.
The Problem with the saying "God can't steer a parked car" is that, while its cute, it isn't biblical. When people of great faith in the Bible don't know what God wants them to do, they don't just run off and make stuff up. They wait on him. (Phil Vischer)
I used to love the old saying, "God don't help no parked cars." I would quote it to others, mostly around the idea of dating- "Just do something, ask someone, start moving, get going and God will direct you." The problem is, as Vischer points out, that doesn't seem to be how the God of the Bible works.
Look at Noah, a guy who actually got to "save the world." He waited 500 years for his chance. What was he doing during the wait?
Noah was a righteous man, blameless among the people of his time, and he walked with God.
Noah walked with God for the first 500 years of his life. That's what God is calling us to do, to wait on Him. To walk with him. Not to run out and and try to manufacture something important to do for Him. God's more interested in our relationship with Him than what we do for Him. Sounds like the message John Eldredge has been giving us in the Men's Group too!
