I'm not sure if the apostle Paul had a big vision as he went on his missionary journeys, or if he just did the work and God blessed it. Either way, he said this in Romans 15: "So from Jerusalem all the way around to Illyricum I have fully proclaimed the Gospel of Christ. ...now that there is no more place for me to work in these regions..."
Let's all dream of being able to say the same thing. What would that look like? My vision is that every person in central Illinois (2 million+ people) would have a chance to hear the Gospel in a conversation. Big visions should drive us to our knees in prayer. They should force us to engage with others and enlist them in the work.
Ultimately though, that big vision needs to boil down to a simple question: What do I do?
What is the smallest possible vision you can have? Maybe it's for your neighborhood, your family, or workplace.
Because if we're not careful, that big vision becomes a place to hide. It can be crippling if we can't bring it to Monday morning. What do I need to do on Monday (or Sunday or Thursday) to start pursuing that vision? We work more on the ideas and plans and goals than we work on the actual work.
If your vision is to write the next great American novel, you shouldn't spend any time on the cover art. You should spend almost all of your time writing. If your vision is to be a great basketball player, you don't need to spend time tracking down the best looking shoe. You need to get to the gym. If your vision is to reach every person in your town with the Gospel, you don't need to set up a neighborhood mapping system. You need to pray and share the Gospel.
What's your big vision? What's your little vision? What are you going to do to get after it?
