To whom coming, as unto a living stone, disallowed indeed of men, but chosen of God, and precious, To whom coming, as unto a living stone - This is a reference to Isaiah 28:16 : Behold, I lay in Zion for a foundation a stone, a tried stone, a precious corner stone, a sure foundation. Jesus Christ is, in both the prophet and apostle, represented as the foundation on which the Christian Church is built, and on which it must continue to rest: and the stone or foundation is called here living, to intimate that he is the source of life to all his followers, and that it is in union with him that they live, and answer the end of their regeneration; as the stones of a building are of no use but as they occupy their proper places in a building, and rest on the foundation.
Disallowed indeed of men - That is, rejected by the Jews. This is a plain reference to the prophecy, Psalms 118:22 : The stone which the builders refused is become the head stone of the corner.
Chosen of God - To be the Savior of the world, and the Founder of the Church, and the foundation on which it rests; As Christ is the choice of the Father, we need have no doubt of the efficacy and sufficiency of all that he has suffered and done for the salvation of a lost world. God can never be mistaken in his choice; therefore he that chooses Christ for his portion shall never be confounded.
Precious - Εντιμον· Honourable. Howsoever despised and rejected by men, Jesus, as the sacrifice for a lost world, is infinitely honorable in the sight of God; and those who are united by faith to him partake of the same honor, being members of that great and glorious body of which he is the head, and stones in that superb building of which he is the foundation.
