"You also, as living stones, are being built up as a spiritual house" (1 Pet. 2:5).
Christ is your life, and you are an integral part of what He is accomplishing in the world.
The Jewish culture of Peter's time centered on the Temple in Jerusalem. Apparently drawing from that picture, Peter used vivid language to teach that God no longer dwells in an earthly, material, temporal house, but in a spiritual house. Christ is the cornerstone, and the spiritual house He is building is comprised of individual believers.
That analogy introduces us to the first spiritual privilege Christians enjoy: union with Christ Himself. That makes Christianity utterly unique among religions. Buddhists are not said to be in Buddha. Muslims are not in Muhammad. A Confucianist is not in Confucius. Only Christians are united with and receive their spiritual life from the object of their worship.
When you came to Christ, the living stone, you also became a living stone yourself. You possess His resurrection life and draw from His spiritual resources. That's what Peter meant when he said that God "has granted to us His precious and magnificent promises, in order that by them you might become partakers of the divine nature" (2 Pet. 1:4).
Ephesians 2:19-22 adds, "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." Christ is the cornerstone of the church, built on the foundation of biblical truth, which is the divine revelation given through the apostles and prophets. Rejoice in the privilege of being united with Christ and learning from His Word!
