The same system of doctrine is inculcated throughout the whole of the sacred volume. Though upwards of fifteen hundred years elapsed between the commencement and the completion of the canon of Scripture; though its authors were variously educated; though they were distinguished, as well by their tastes, as by their temperaments; and though they lived in different countries and in different ages; all the parts of the volume called the Bible exhibit the clearest indications of unity of design. Each writer testifies to the "one faith," and each contributes something to its illustration. Thus it is that, even at the present day, every book in the canon is "good to the use of edifying." The announcements made to our first parents will continue to impart spiritual refreshment to their posterity of the latest generations; and the believer can now give utterance to his devotional feelings in the language of the Psalms, as appropriately as could the worshipper of old, when surrounded by all the types and shadows of the Levitical ceremonial. The Old Testament is related to the New as the dawn to the day, or the prophecy to its accomplishment. Jesus appeared merely to consummate the Redemption which "the promises made to the fathers" had announced. "Think not," said he, "that I am come to destroy the law or the prophets, I am not come to destroy but to fulfil." [189:1] The mission of our Lord explained many things which had long remained mysterious; and, in allusion to the great amount of fresh information thus communicated, He is said to have "brought life and immortality to light through the gospel." [189:2]
