As I pondered Billy's position, it reminded me that all Christians should be construciton coordinators in a way. The Bible tells us plainly in Ephesians 4:29: Do not let any unwholesome talk come out of your mouths, but only what is helpful for building others up according to their needs, that it may benefit those who listen.
The hardest part of this command is the only "only." How many of us even monitor the words that come out of our mouths, much less seek to intentionally use words to build up other people? That's what's the "stranger" alternative to be a World Changing Construction Coordinator...that someone who has been adopted into God's family through Christ would miss opportunities to "build" something important (even eternal), and yet waste words tearing down and destroying! So be a part of some kind of construction today...it's what we're made for!
