Gospels, New Testament, sermon on the mount, teachings of Jesus 

Though we are told at the beginning of chapter v that it was His "disciples" whom Christ here taught, yet it is equally clear from the closing verses of chapter vii that this Sermon was spoken in the hearing of the multitudes. This must be steadily borne in mind throughout, for while it contains much instruction for believers in connection with their living a good, honest, and blessed life, yet not a little in it is evidently designed for unbelievers, particularly those sections which contain a most searching setting forth of the spiritual nature of His kingdom and the character of those who enter and enjoy its privileges. Romish teachers have greatly erred, for they insist that Christ here propounded a new Law—far more perfect than the Law of Moses—and that He delivered now entirely new counsel to His disciples, which was never given in the Law or the Prophets; whereas His intention was to clear the true meaning of the Law and the Prophets, which had been greatly corrupted by the Jewish doctors. But we will not further anticipate what we shall (D. V.) contemplate more fully in the studies to follow. - from Amzon
