"A variety of purposes can be discovered to explain the insertion of the old covenant order and its typal kingdom into the course of redemptive history. Of central importance was the creation of the proper historical setting for the advent of the Son of God and his earthly mission (cf. Rom 9:5). In accordance with the terms of his covenant of works with the Father he was to come as the second Adam in order to undergo a representative probation and by his obedient and triumphant accomplishment thereof to establish the legal ground for God’s covenanted bestowal of the eternal kingdom of salvation on his people. It was therefore expedient, if not necessary, that Christ appear within a covenant order which, like the covenant with the first Adam, was governed by the works principle (cf. Gal 4:4). The typal kingdom of the old covenant was precisely that. Within the limitations of the fallen world and with modifications peculiar to the redemptive process, the old theocratic kingdom was a reproduction of the original covenantal order. Israel as the theocratic nation was mankind stationed once again in a paradise-sanctuary, under probation in a covenant of works. In the context of that situation, the Incarnation event was legible; apart from it the meaning of the appearing and ministry of the Son of Man would hardly have been perspicuous. Because of the congruence between Jesus’ particular historical identity as the true Israel, born under the law, and his universally relevant role as the second Adam, the significance of his mission as the accomplishing of a probationary assignment in a works covenant in behalf of the elect of all ages was lucidly expressed and readily readable."Kline, M.
