A good word from Doug Wilson for both missions “goers” and “senders”:
What you practice at home is the show you take on the road. What you grow in your fields is what you load on the trucks. Compassing sea and land doesn’t generate a new message. The way you live when you get on the plane is going to be the single best indicator of how you live when you get off the plane. In short, don’t expect geographical location to fix anything.
