This must be learned from an examination of the book itself, and the views entertained on this point will be determined, in a great measure, by the principles which are adopted in interpreting it. From the examination which I have given of the book, and the methods of interpretation which I have adopted, it seems to me that the matter and design of the book may be expressed in the following specifications:―― 1. It was composed in a time of persecution, and in view of the persecutions and hostilities, external and internal, to which the church was then, and would be exposed. Christianity was then in its infancy. It was comparatively feeble. It encountered the opposition of the world. The arm of the civil power was raised to crush it. It was also exposed to the attacks of internal foes, and persecutions would arise from its own bosom, and formidable enemies in future times would seem to endanger its very existence. Heresies, and divisions, and corruptions of doctrine and of practice, might be expected to exist in its own bosom; times of conflict and darkness would come; changes would occur in governments that would deeply affect the welfare of the church; and there might be periods when it would seem to be doubtful whether the true church would not become wholly extinct. The faith of Christians was, doubtless, sorely tried in the persecution which existed when the book was written, and would be in like manner often sorely tried in the corruptions and persecutions of future ages. 2. The Apocalypse is designed to meet this state of feeling by furnishing the assurance that the gospel would ultimately prevail; that all its enemies would be subdued, and the kingdom of the Messiah set up over all the world. It was intended to impart consolation to the people of God in all ages, and in all forms of persecution and trial, by the assurance that the true religion would be at last triumphant, thus furnishing an illustration of the truth of the declarations of the Saviour respecting the church, that the “gates of hell should not prevail against it,” Mat. xvi. 18. Hence everything in the book tends to the final triumph of the gospel; and hence at the close (chap. xx.), we have the assurance of its far-spread diffusion over the earth, for a period of a thousand years, and (chap. xxi., xxii.) a graphic view of the state of the redeemed when they shall be delivered from sin and woe, and when all tears shall be wiped away from their eyes.
