The third reason God wills work is that by working we provide for the needs of those who can't provide for their own . The promise that if you sweat you shall eat is not absolute. All that is part of the curse which sin brought on to the world. But God in his mercy wills that the work of the able-bodied in prosperous times supply the needs of the helpless, especially in hard times. Three passages of Scripture make this plain.
Work is a way of love.
Finally, God wills work as a way of building bridges for the gospel . In our work we are usually in the world. We rub shoulders with unbelievers. If we do our work in reliance on God's power, according to his pattern of excellence and thus for his glory, we will build bridges for the gospel so that people can cross over and be saved. There is a very close connection between the way we do our work and the attitude that unbelievers will have toward the gospel that makes us tick.
