The passover was a family duty, by which they were yet further sanctified to God. Yea, it is especially to be observed how in the New Testament, the Holy Ghost doth imitate the language of the Old, and speak of God's people as of holy societies, as the Jews were. As in many prophecies it was foretold that nations and kingdoms should serve him (of which I have spoken more in my book of Baptism); and among those who should "mourn over him whom they have pierced" in gospel times, when the spirit of grace and supplication is poured forth, are "the family of the house of David apart, and their wives apart; the family of the house of Nathan apart, and their wives apart; every family, even all the families that remained, apart, and their wives apart," Zech. xi. 12-14. So Christ sendeth his disciples to "baptize nations," having discipled them; and "the kingdoms of the world shall become the kingdoms of the Lord, and his Christ." And as, Exod. xix. 5, 6, God saith of the Jews, "Ye shall be a peculiar treasure to me above all people; and ye shall be unto me a kingdom of priests, and a holy nation;" so doth Peter say of all christians, 1 Pet. ii. 5-7, 9, "Ye also, as living stones, are built up a spiritual house, an holy priesthood, to offer up spiritual sacrifices acceptable to God by Jesus Christ. But ye are a chosen generation, a royal priesthood, an holy nation, a peculiar people, that you should show forth the praises of him that hath called you out of darkness into his marvellous light." Mark how fully this text doth prove all that we are about. It speaks of christians collectively, as in societies, and in societies of all the most eminent sorts: "a generation;" which seems especially to refer to tribes and families: "a priesthood, nation, people;" which comprehendeth all the orders in the nation ofttimes. And in all these respects they are holy, and peculiar, and chosen, to show, that God's people are sanctified in these relations and societies. And then mark the end of this sanctification; ver. 5, "to offer up spiritual sacrifices acceptable to God by Jesus Christ;" ver. 9, "to show forth the praises of him that hath called you," &c.
