You also, like living stones, are being built into a spiritual house to be a holy priesthood, offering spiritual sacrifices acceptable to God through Jesus Christ. 1 Peter 2:5
Peter made it clear in the previous verse that Jesus is the "living Stone." In the following verse, Peter makes it clear that by "Stone" he, like Paul, means "cornerstone" (1 Peter 2:6, Ephesians 2:20). Jesus is the One upon which all things are built and by which all things are aligned. All spiritual life comes through and depends on Him.
Believers, because of our relationship with Jesus, are like "living stones." Our new birth, brought about by the work of Christ, gives us true life, now and forever. Indwelt by the Holy Spirit, we are a "spiritual house," the "temple of the living God" (2 Corinthians 6:16). Continuing with the Old Testament analogy, Peter says that we are "to be a holy priesthood."
There are many aspects of the Old Testament priesthood that I could use to compare with believers now, but let's focus on two. First, the priests had direct access to God. We have that same access through Jesus Christ. He is seated at the right hand of God interceding for us (Romans 8:34). Second, the priests represented God to the people. Now that assignment is ours. How are you doing with that responsibility? As my mom used to say, "You may be the only Bible some people ever read."
Father, thank You for making us "like living stones" through your Son. Thank You for the direct access we have to You through Jesus. Today may we represent You well in all we do and say. In Jesus' name. Amen.
