And night shall be no more: and they shall have no need of light of a lamp, and light of the sun; because the Lord God will give them light, and they shall reign to the ages of ages" (xxii. 1-5). The foregoing citations, and indeed the whole tenor of the contents of the Apocalypse, clearly point to the {110} conclusion that what is symbolized by "the Lamb" and "the Lamb slain" runs through all it teaches respecting the course of experience and future destination of the race of man--is "the lamp" that enlightens the whole. Now, I think I may assert that the reason this is so is given by the arguments adduced in this Essay. It has been maintained that on the day that Adam fell into disobedience by the wiles of Satan, his Creator made a promise by covenant that he and his offspring should in the end be freed from the power of Satan and evil, and partake of immortality. The terms of the covenant were that man must pass through toil, and pain, and death, that thereby his spirit might be formed for receiving the gift of an immortal life. Evidence of an intelligent belief of the efficacy of these conditions was given by the faithful of old by their sacrificing clean animals, and surety for the fulfilment of the covenant was given on God's part by a favourable acceptance, either directly or mediately, of this expression of their faith. In process of time the only begotten Son of God, out of sympathy with suffering humanity, and from knowledge of his Father's purpose towards us, satisfied in his own person the very same conditions, and thus at once exemplified and justified the means by which that purpose is accomplished. At the same time he made sure the grounds for belief of the fulfilment of the covenanted promise, first by marvellous {111} works before he suffered, which showed that he had command over all the ills of humanity, and after his death, by resurrection from the grave the third day, which gave proof of the reality of a power that could overcome death. The miracles of Christ are an essential part of the work of his ministry, inasmuch as they were needed to prove that he possessed power greater than that of his adversaries, and consequently that he submitted _voluntarily_ to be "led as a _lamb_ to the slaughter," and to endure all the pain and indignities of the cross. Out of love towards those whom he vouchsafes to call his brethren, he showed how they must undergo physical suffering and the pains of death in order that their spirits might be formed for an endless life. It was with understanding and belief that the way to life was made sure by fellowship with Christ in suffering, that some of the most favoured of his faithful followers, apostles and apostolic men, willingly suffered after his example.
