"The moral struggle between godliness and ungodliness, so vividly depicted in the Psalms, culminates in Holy Scripture, in the life of the Incarnate Son of God upon earth. It only remains to show that the Psalms themselves definitely anticipated this culmination. Now there are in the Psalter at least three psalms of which the interest evidently centers in a person distinct from the speaker, and which, since they cannot without violence to the language be interpreted of any but the Messiah, may be termed directly and exclusively Messianic. We refer to Ps. ii., xlv., cx.; to which may perhaps be added, Ps. lxxii. It would be strange if these few psalms stood, in their prophetical significance absolutely alone among the rest. And hence the impossibility of viewing the psalms generally, notwithstanding the drapery in which they are outwardly clothed, as simply the past devotions of the historical David or the historical Israel. The national hymns of Israel are indeed also prospective; but in general they anticipate rather the struggles and the triumphs of the Christian Church than those of Christ himself."
