1 Peter 2: 4 - 9
4 Come to him, to that living stone, rejected by men but in God's sight chosen and precious;
5 and like living stones be yourselves built into a spiritual house, to be a holy priesthood, to offer spiritual sacrifices acceptable to God through Jesus Christ.
6 For it stands in scripture: "Behold, I am laying in Zion a stone, a cornerstone chosen and precious, and he who believes in him will not be put to shame."
7 To you therefore who believe, he is precious, but for those who do not believe, "The very stone which the builders rejected has become the head of the corner,"
8 and "A stone that will make men stumble, a rock that will make them fall"; for they stumble because they disobey the word, as they were destined to do.
9 But you are a chosen race, a royal priesthood, a holy nation, God's own people, that you may declare the wonderful deeds of him who called you out of darkness into his marvelous light.
