And say, As I live forever."
(Deut. xxxii. 39, 40.)
"And Jehovah said, Behold, the man is become as one of us, to know good and evil; and now, lest he put forth his hand, and take also the tree of life, and live forever." (Gen. iii. 22.)
These two sole instances of the use of the expression "eternal life" in the Old Testament (with the exception of another instance in the apocryphal book of Daniel) determine clearly the Hebraic conception of the life of man and the life eternal. Life itself, according to the Hebrews, is eternal, is in God; but man is always mortal: it is his nature to be so. According to the Jewish doctrine, man as man, is mortal. He has life only as it passes from one generation to another, and is so perpetuated in a race. According to the Jewish doctrine, the faculty of life exists in the people. When God said, "Ye may live, and not die," he addressed these words to the people. The life that God breathed into man is mortal for each separate human being; this life is perpetuated from generation to generation, if men fulfil the union with God, that is, obey the conditions imposed by God. After having propounded the Law, and having told them that this Law was to be found not in heaven, but in their own hearts, Moses said to the people:—
"See, I have set before thee this day life and good, and death and evil; in that I command thee this day to love the Eternal, to walk in his ways, and to keep his commandments, that thou mayest live.... I call heaven and earth to witness against you this day, that I have set before thee life and death, the blessing and the curse: therefore choose life, that thou mayest live, thou and thy seed: to love the Eternal, to obey his voice, and to cleave unto him: for he is thy life, and the length of thy days." (Deut. xxx. 15-19.)
The principal difference between our conception of human life and that possessed by the Jews is, that while we believe that our mortal life, transmitted from generation to generation, is not the true life, but a fallen life, a life temporarily depraved,—the Jews, on the contrary, believed this life to be the true and supreme good, given to man on condition that he obey the will of God. From our point of view, the transmission of the fallen life from generation to generation is the transmission of a curse; from the Jewish point of view, it is the supreme good to which man can attain, on condition that he accomplish the will of God. It is precisely upon the Hebraic conception of life that Jesus founded his doctrine of the true or eternal life, which he contrasted with the personal and mortal life. Jesus said to the Jews:—
"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.
If we believe that Jesus' words concerning the last judgment and the consummation of the age, and other words reported in the Gospel of John, are a promise of a life beyond the grave for the souls of men,—if we believe this, it is none the less true that his teachings in regard to the light of life and the kingdom of God have the same meaning for us that they had for his hearers eighteen centuries ago; that is, that the only real life is the life of the son of man conformable to the will of the Giver of Life. It is easier to admit this than to admit that the doctrine of the true life, conformable to the will of the Giver of Life, contains the promise of the immortality of life beyond the grave.
