Living Stones...

... like newborn babes, long for the pure milk of the word, that by it you may grow in respect to salvation, if you have tasted the kindness of the Lord. And coming to Him as to a living stone, rejected by men, but choice and precious in the sight of God, you also, as living stones, are being built up as a spiritual house for a holy priesthood, to offer up spiritual sacrifrices acceptable to God through Jesus Christ.

For this is contained Scripture: "Behold I lay in Zion a choice stone, A precious corner stone, and he who believes in Him shall not be disappointed." (Is 28:16)
This precious value, then is for you who believe. But for those who disbelieve, "The stone which the builders rejected, this became the very corner stone," (Ps. 118:22) and "A stone of stumbling and a rock of offense"; (Is 8:14) for they stumble because they are disobedient to the word, and to this doom they were also appointed.
But you are a chosen race, a royal priesthood, a holy nation, a people for God's own possession, that you may proclaim the excellencies of Him who has called you out of darkness into His marvelous light; for you once were not a people, but now you are the people of God; you had not received mercy, but now you have received mercy. (Hosea 1:10, 2:23)
