4 To whom coming, a living stone, cast away indeed as worthless by men, but with God chosen, precious, 5 yourselves also, as living stones, are being built up a spiritual house, a holy priesthood, to offer spiritual sacrifices acceptable to God by Jesus Christ. 6 Because it is contained in the scripture: Behold, I lay in Zion a corner stone, elect, precious: and he that believes on him shall not be put to shame. 7 To you therefore who believe [is] the preciousness; but to the disobedient, the stone which the builders cast away as worthless, this is become head of [the] corner, 8 and a stone of stumbling and rock of offence; [who] stumble at the word, being disobedient to which also they have been appointed.
9 But ye [are] a chosen race, a kingly priesthood, a holy nation, a people for a possession, that ye might set forth the excellencies of him who has called you out of darkness to his wonderful light; 10 who once [were] not a people, but now God's people; who were not enjoying mercy, but now have found mercy.
Matthew Henry's Commentary on 1 Peter 2:4-10
Commentary on 1 Peter 2:1-10
(Read 1 Peter 2:1-10)
Evil-speaking is a sign of malice and guile in the heart; and hinders our profiting by the word of God. A new life needs suitable food. Infants desire milk, and make the best endeavours for it which they are able to do; such must be a Christian's desires after the word of God. Our Lord Jesus Christ is very merciful to us miserable sinners; and he has a fulness of grace. But even the best of God's servants, in this life, have only a taste of the consolations of God. Christ is called a Stone, to teach his servants that he is their protection and security, the foundation on which they are built. He is precious in the excellence of his nature, the dignity of his office, and the glory of his services. All true believers are a holy priesthood; sacred to God, serviceable to others, endowed with heavenly gifts and graces. But the most spiritual sacrifices of the best in prayer and praise are not acceptable, except through Jesus Christ. Christ is the chief Corner-stone, that unites the whole number of believers into one everlasting temple, and bears the weight of the whole fabric. Elected, or chosen, for a foundation that is everlasting. Precious beyond compare, by all that can give worth. To be built on Christ means, to believe in him; but in this many deceive themselves, they consider not what it is, nor the necessity of it, to partake of the salvation he has wrought. Though the frame of the world were falling to pieces, that man who is built on this foundation may hear it without fear. He shall not be confounded. The believing soul makes haste to Christ, but it never finds cause to hasten from him. All true Christians are a chosen generation; they make one family, a people distinct from the world: of another spirit, principle, and practice; which they could never be, if they were not chosen in Christ to be such, and sanctified by his Spirit. Their first state is a state of gross darkness, but they are called out of darkness into a state of joy, pleasure, and prosperity; that they should show forth the praises of the Lord by their profession of his truth, and their good conduct. How vast their obligations to Him who has made them his people, and has shown mercy to them! To be without this mercy is a woful state, though a man have all worldly enjoyments. And there is nothing that so kindly works repentance, as right thoughts of the mercy and love of God. Let us not dare to abuse and affront the free grace of God, if we mean to be saved by it; but let all who would be found among those who obtain mercy, walk as his people.
