" Finally we should note that the Lord commands everyone of us in all the actions of our life to be faithful in our calling. For He knows that the human mind burns with restlessness, that it is swept easily hither and thither, and that it's ambition to embrace many things at once is insatiable.
Therefore to prevent that general confusion being produced by our folly and boldness, He has appointed to everyone his particular duties in the different spheres of life. And that no one may go beyond his limits, He has called such spheres of life vocations, or callings. Every individual's sphere of life therefore, is a post assigned him by the Lord that he may not wander about in uncertainty all the days of his life. And so necessary is this distinction, that in His sight all our actions are measured by it, and often very differently from the judgment of human reason or philosophy.
Our present life, therefore, will be best regulated if we keep always keep our calling in mind. No one will then be tempted by his own boldness to dare to undertake what is not compatible with his own calling, because he will know it is wrong to go beyond his limits. Anyone who is not in the front ranks should be content to accomplish his private task, and should not desert the place where the Lord has put him. It will be no small comfort for his cares, labors, troubles, and other burdens, when a man knows that in all these matters God is his guide.
The magistrate will then carry out his office with greater willingness.
The father of a family will then perform his duties with more courage.
And everyone in his respective sphere of life will show more patience, and will overcome the difficulties, cares, miseries, and anxieties in his path, when he will be convinced that every individual has his task laid upon his shoulders by God.
If we follow our divine calling, we shall receive this unique consolation that there is no work so mean and so sordid that does not look truly respectable and highly important in the sight of God."
