Mother is a vocation. Folding laundry is a job.
Husband is a vocation. Assembling porch gliders is a job.
Breadwinner is a vocation. Tinker, tailor, soldier, and spy are jobs.
Vocation is not our license to do whatever in the world we want with our lives in nomine Jesu. In fact, vocation obligates us to direct our energies and resources to others. This requires us to sacrifice pride and comfort, for others often need things beneath our dignity. The beauty of vocation is not that whatever we're good at is good for us to do, but that whatever God ordains for us to do is good.
Vocation cannot be a front for pursuing dreams. Vocation does not mean "stewardship of my gifts" or "whatever the heck I'm doing right now." Only a liberal arts major or a Commissioned Minister could believe this. Not everyone has the privilege of pursuing the job they would most enjoy, or even a job where their gifts lie.
Those who are called to the work of breadwinning must put winning sufficient bread ahead of their personal interests, and God bless them for doing it. We wouldn't think much of a father who spent his time waiting for a major record label to pick up one of his ditties while his children suffered want for the sake of his musical gift. We would think much of him if he got a job that supported his family adequately and used his musical talent in an avocational capacity in the service of his church. Christians do not claim some right to do what we want or like, because our neighbors very often need us to make a regular habit of doing otherwise. In fact, Christians don't claim rights at all; only Americans do.
Breadwinners should win bread. They should keep in mind the danger of gathering more than they need. If they are able to win bread by means of their favored talents, they can thank God for his benevolence. They can either take comfort or derive humility from knowing that the way they win bread is not, in fact, a matter of vocation. And all people can use their gifts, talents, and interests avocationally for the glory of God and the good of His people.
