Do not fall into the mistake of supposing that the opening verses of the Sermon on the mount set forth how we are to be saved, or you may cause your soul to stumble. You will find the fullest light upon that matter in other parts of our Lord’s teaching, but here he discourses upon the question, “Who are the saved?” or, “What are the marks and evidences of a work of grace in the soul?” Who should know the saved so well as the Savior does? The shepherd best discerns his own sheep, and the Lord himself alone knoweth infallibly them that are his. We may regard the marks of the blessed ones here given as being the sure witness of truth, for they are given by him who cannot err, who cannot be deceived, and who, as their Redeemer, knows his own.
