Verse 10.— In this the children of God. Here, a sure mark of distinction is drawn between the children of God and the children of the devil. It is easy to tell one from the other. The child of God habitually per­forms good acts, deeds and works, and with a real affection loves his brother, while the children of the devil manifest no such fruits. The rule of measurement is plainly desig­nated. The children of God show by their pure lives, their constant endeavors to do good, their affection not only for the distressed, but for all, who their Father is. By the same rule the parentage of the evil may be easily determined.
