"_Search the Scriptures; for in them ye think ye have eternal life: and they are they which testify of me._" (John v. 39.) To the young man who asked what he must do to have eternal life, Jesus said in reply, "_If thou wilt enter into life, keep the commandments_." He did not say "the eternal life," but simply "the life" (Matt. xix. 17). To the same question propounded by the scribe, the answer was, "_This do, and thou shalt live_" (Luke x. 28), once more promising life, but saying nothing of eternal life. From these two instances, we know what Jesus meant by eternal life; whenever he made use of the phrase in speaking to the Jews, he employed it in exactly the same sense in which it was expressed in their own law,--the accomplishment of the will of God. In contrast with the life that is temporary, isolated, and personal, Jesus taught of the eternal life promised by God to Israel--with this difference, that while the Jews believed the eternal life was to be perpetuated solely by their chosen people, and that whoever wished to possess this life must follow the exceptional laws given by God to Israel,--the doctrine of Jesus holds that the eternal life is perpetuated in the son of man, and that to obtain it we must practise the commandments of Jesus, who summed up the will of God for all humanity. As opposed to the personal life, Jesus taught us, not of a life beyond the grave, but of that universal life which comprises within itself the life of humanity, past, present, and to come. According to the Jewish doctrine, the personal life could be saved from death only by accomplishing the will of God as propounded in the Mosaic law. On this condition only the life of the Jewish race would not perish, but would pass from generation to generation of the chosen people of God. According to the doctrine of Jesus, the personal life is saved from death by the accomplishment of the will of God as propounded in the commandments of Jesus. On this condition alone the personal life does not perish, but becomes eternal and immutable, in union with the son of man. The difference is, that while the religion given by Moses was that of a people for a national God, the religion of Jesus is the expression of the aspirations of all humanity. The perpetuity of life in the posterity of a people is doubtful, because the people itself may disappear, and perpetuity depends upon a posterity in the flesh. Perpetuity of life, according to the doctrine of Jesus, is indubitable, because life, according to his doctrine, is an attribute of all humanity in the son of man who lives in harmony with the will of God.
