What does it mean to be a spiritual house in Christ?

1 Peter 2:5 states that believers, as 'lively stones,' are built up a spiritual house, representing the collective body of Christ. This imagery highlights our identity as a church, where each member contributes to the fulfillment of God’s purposes. As this spiritual house, we are called to offer spiritual sacrifices, which signify our worship, service, and lives devoted to glorifying God through Jesus Christ. It demonstrates that our connection to Christ shapes our identity and mission as His people, lifting us above the old covenant's demands and inviting us to live by the Spirit.
