John Wesley on Luke 16:15

And he said to them, Ye are they who justify yourselves before men - The sense of the whole passage is, that pride, wherewith you justify yourselves, feeds covetousness, derides the Gospel, Lu 16:14, and destroys the law, Lu 16:18. All which is illustrated by a terrible example. Ye justify yourselves before men - Ye think yourselves righteous, and persuade others to think you so.
