It is her calling to be a good mother, and to make a true home for her household.
Her duty is to do always her very best to make her home beautiful, bright, happy, a fit place for her children to grow up in.
Faithfulness requires that she do always such service as a mother, that Jesus shall say of her home-making, "She hath done what she could." To do less than her best is to fail in fidelity.

Suppose that her hand should slack, that she should grow negligent, would she not clearly be robbing God?
For even God cannot make a beautiful home for her children without her.
So we may apply the principle to all kinds of work.

The faithfulness which God requires must reach to everything we do, to the way the child gets its lessons and recites them, to the way the dressmaker and the tailor sew their seams, to the way the blacksmith welds the iron, and shoes the horse, to the way the plumber puts the pipes into the new building and looks after the drainage, to the way the carpenter does his work on the house, to the way the bridge-builder swings the bridge over the stream, to the way the clerk represents the goods, and measures or weighs them.

"Be thou faithful" is the word that rings from heaven in every ear.

God's word for the doing of every piece of work that any one does.
