We have argued above that the patriarchs Noah { 28} and Abraham testified their belief and acceptance of the covenant of life by sacrifice. But in the patriarchal times the only surety for the fulfilment of the promise was the direct word of God. With the exception of what is said of Melchisedek, who typified a High Priest to come, no mention is made of the mediation of priests till the priesthood of Aaron was regularly constituted. From that time the priest was mediator between God and the people, and in virtue of his office gave assurance of the fulfilment of the covenant to those who, by offering clean animals for sacrifice, signified their acceptance of its conditions. The priest gave such assurance by mediatorially receiving the offerings, and representing, by sprinkling the blood of the slain animals, _the purifying effect of the suffering of death_. After the ordinances of the law had been instituted, Moses said to the people, "I have set before you life and death: choose life" (Deut. xxx. 19). Seeing that no one can escape the death which is the termination of the present life, this choice between life and death necessarily refers to the covenanted life, the fulfilment of the conditions of which secures from death in the world to come. The author of the Apocryphal Book 2 Esdras, who was wiser, I think, than the author of "The Divine Legation of Moses," has shown that he so understood the passage; for after saying (vii. 48, 44), "The day of doom shall be the end of this time, and the { 29} beginning of the immortality for to come, wherein corruption is past, intemperance is at an end, infidelity is cut off, righteousness is grown, and truth is sprung up," he adds (in _v._ 59) with reference to this description of the life to come, "This is the life whereof Moses spake unto the people while he lived, saying, Choose thee life, that thou mayest live."
Sacrifice remained the chief symbol of religious faith up to the time of that great sacrifice of the Son of God, the acceptance of which by the Father sealed the covenant of everlasting life, and made all other sureties sure. The ground of assurance lies in the fact that Jesus Christ in his life and death went through all the experience whereby _our_ spirits are formed for immortality. "He learned obedience by the things that he suffered" (Heb. v. 8). He was made perfect "through sufferings" (Heb. ii. 10). "He made him to be sin (_hamartian_; compare Gal. iii. 13) for us, who knew no sin, that we might be made the righteousness of God in Him" (2 Cor. v. 21). Joining with these passages that remarkable one in which Christ is spoken of as "a priest who is made according to the power of an indissoluble (_akatalytou_) life" (Heb. vii. 16), it is evident that our community with him in suffering, in death, and, as we have reason to hope, in resurrection, is ample surety to us for the fulfilment of the covenant of immortality. For as death is the dissolution of life, indissoluble { 30} life means exemption from death, and is, therefore, identical with immortality.
