God WILL unfold purpose as you travel. The little “purposes” always delight me the most–small ways he uses me. Because we don’t spend a lot of time in one place, I frequently don’t know much of a person’s life story, but sometimes I sense that a conversation we’re having is a clarifying one for them. There is also the volunteer work we do. It won’t be hard for you to find little ways for your kids to fit into local projects, soup kitchens, Salvation Army, etc. that will help them understand being Jesus’ hands and feet in action. It will be an exciting, fulfilling way for you to raise your children. You are offering them, firsthand, things that other children only read about in books!
