19So then you are no longer strangers and aliens, but you are fellow citizens with the saints, and are of Gods household,
20having been built on the foundation of the apostles and prophets, Christ Jesus Himself being the corner stone,
21in whom the whole building, being fitted together, is growing into a holy temple in the Lord, 22in whom you also are being built together into a dwelling of God in the Spirit. Ephesians 2:17-22 NASB
As you come to him, a living stone rejected by men but in the sight of God chosen and precious, 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. 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.
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,
and
A stone of stumbling, and a rock (petra) of offense.
They stumble because they disobey the word, as they were destined to do.
