1 Peter 2:1-8 (ESV)
A Living Stone and a Holy People
2:1 So put away all malice and all deceit and hypocrisy and envy and all slander. 2 Like newborn infants, long for the pure spiritual milk, that by it you may grow up into salvation— 3 if indeed you have tasted that the Lord is good.
4 As you come to him, a living stone rejected by men but in the sight of God chosen and precious, 5 you yourselves like living stones are being built up as 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 whoever believes in him will not be put to shame.”
7 So the honor is for you who believe, but for those who do not believe,
“The stone that the builders rejected
has become the cornerstone,” 
“A stone of stumbling,
and a rock of offense.”
They stumble because they disobey the word, as they were destined to do.
