I Peter 2:5
you also, as living stones, are being built up a spiritual house, a holy priesthood, to offer up spiritual sacrifices acceptable to God through Jesus Christ.
I am a living stone built upon a spiritual house whose foundation is Jesus Christ. I am valuable for the structural integrity of the house. If I leave my post, I will be tossed to and fro by the world, and the wall will weaken. If I remain, I am protected, and the wall remains strong. My Father has strategically placed me, and I will hold fast.

I Peter 2:6-7
Therefore it is also contained in the Scripture, “Behold, I lay in Zion A chief cornerstone, elect, precious, and he who believes on Him will by no means be put to shame.” Therefore, to you who believe, He is precious; but to those who are disobedient, “The stone which the builders rejected has become the chief cornerstone,”
Psalm 133:1
Behold, how good and pleasant it is when brothers dwell in unity!
