In regard of the Divine workings themselves, especially when they come before us in the general forms of judgments on individuals or nations, all we may presume safely to do is to regard them as manifestations of Divine righteousness in judicial relations or contradistinctions to the sins or transgressions of men. In reference, however, to the moral difficulties connected with recorded human actions, we may venture to go farther, and to take into consideration the fact already referred to of the gradual nature of God's revelation, and all the modifying thoughts which such a fact brings with it. It is thus not only right, but necessary, to accept as our guide in all such investigations or discussions this sober spiritual principle,--that the Old Testament must be interpreted from the stand-point of the New Testament, and under the fuller light which is afforded by the later dispensation. If we cling to these two great truths--first, that the history of the past, as we find it in the Old Testament, ever involves a reference to final purposes; and, secondly, that every attempt to realize the deeper significance of that history must use Christianity as its basis--we shall probably find our way in this difficult domain of speculation as far and as safely as the finite powers of man can be deemed capable of advancing; we shall see as clearly as we can be permitted to see, when poor human reason is endeavouring to survey the adorable mysteries that surround the recorded workings of the manifold wisdom of God. The second portion of this third group is more especially devoted to difficulties connected with the New Testament, the first place being naturally reserved for the questions relating to the life of our Lord and the Gospel narrative. The first lecture is thus directed to a consideration of the Mythical Theories of Christianity; the second to the Evidential Value of St. Paul's Epistles. As has already been mentioned, the lecture on St. John's Gospel, which would have occupied a position between the two just specified, owing to the request of the writer, has not been published, and the series in this part of it has in consequence suffered. The two remaining lectures, viz., that on Christ's Teaching and Influence on the World, and that which follows it, on the Completeness and Adequacy of the Evidences of Christianity, form the last group, and worthily conclude the interesting series. A third lecture on the additional strength which is brought to the evidences of Christianity by the convergence of various lines of independent testimony, was intended to have been added to this group, but for this important and comprehensive subject, as in the case of another subject recently mentioned, the Committee were not able to procure a lecturer.
