1 Peter 2:4-8
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 sacrifices acceptable to God through Jesus Christ. For this is contained in Scripture: 'Behold I lay in Zion a choice stone, a precious corner stone, And he who believes in Him shall not be disappointed.' 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,' and, 'A stone of stumbling and a rock of offense'; for they stumble because they are disobedient to the word, and to this doom they were also appointed.
1 Corinthians 3:9
For we are God's fellow workers; you are God's field, God's building.
So then you are no longer strangers and aliens, but you are fellow citizens with the saints, and are of God's household, Having been built upon the foundation of the apostles and prophets, Christ Jesus Himself being the corner stone, in whom the whole building, being fitted together is growing into a holy temple in the Lord; in whom you also are being built together into a dwelling of God in the Spirit.
