Now to the one who works, his wages are not counted as a gift but as his due.
4. To him indeed who works, etc. It is not he, whom he calls a worker, who is given to good works, to which all the children of God ought to attend, but the person who seeks to merit something by his works: and in a similar way he calls him no worker who depends not on the merit of what he does.
