Give ear to another story. A master of a house made a vine garden, and put a wall round it, and made a place for crushing out the wine, and made a tower, and let it out to field-workers, and went into another country.
It is as when a man who is in another country for a time, having gone away from his house, and given authority to his servants and to everyone his work, gives the porter an order to keep watch.
For this cause, my dear brothers, be strong in purpose and unmoved, ever giving yourselves to the work of the Lord, because you are certain that your work is not without effect in the Lord.
