Verse 19— Brethren, if any of you do err. It is the duty of Christians to be solicitous for the wel­fare of each other, both in temporal and spiritual affairs. And in case a brother should do wrong, should be seduced from the path of Christian duty, and he should be turned or brought back to his duty from which he strayed by the watchful, careful, loving aid of a brother, the latter not only performs an act which meets the approval of the great Head of the Church, but will have an additional honor con­ferred upon him, concerning which we shall see in the succeeding verse.
