Covenant sacrifice of Abraham, consisting of the red heifer, whose ashes were for purification; the she-goat of three years, for a sin-offering; the ram for a burnt-offering; the turtle-dove and the young pigeon, for a purification sacrifice and for a sin-offering, intimating that not merely did he, as a covenant-head, represent the rich who should present of their flocks and herds to the Lord, but of the poor, who of their poverty should present offerings absolutely less valuable, but not the less acceptable;--these offerings pointed out that the Covenant of God should be laid hold upon when the shadows which preceded the glorious reality of the "One Sacrifice" that had been foreordained would have come to an end, and there should succeed sacrifices spiritual in their stead, acceptable to God through Jesus Christ. And circumcision, prefiguring Christ given for a covenant of the people, who, in the nature of man shedding his blood, should ratify God's covenant; and marking the people of God, sealing to them the Covenant of Grace, and pointing out their newness of life, regeneration, and deliverance from the vileness of sin, testified to the claims of obedience to the mandate of God in Covenant, which none could, but at the greatest peril, disregard. These types and others all pointed to the Redeemer. To the work which he had, from the days of eternity, Covenanted to perform, they gave prospective testimony. But of the effects of his mighty working upon the hearts of men, in leading them to keep his Covenant, they were not the less appointed symbols, nor were they less designed to teach that, but for the arrangements of that Covenant which had been made with him, there had not been made such manifestations of the power of his grace.
