We depend on people and churches, not the sweat of our brow. We don't live under the gun of financial cause and effect. Most jobs are filled by either missionaries or local people, so there isn't much for us to do. We live with constant change, so we rarely stay anywhere long enough to learn perseverance. There's a constant round of schooling, vacations, furloughs, and moves to new stations.
Friends come and go all the time.
In addition to what I mentioned above, consider the following ideas. First, our parents can teach us accountability. They cannot permit laziness. Biblical principles about work must be taught and practiced. Granted that we may not face the same kind of accountability hat other employees do, but our parents should teach us that we are accountable to our supporting churches and individual donors.
