A lot of Christians struggle with their identity in Christ. When they don’t know who they are, they don’t know what to do. When they don’t know what to do, they don’t know how to behave. So we have a world that is quite a mixed bag. But Peter gives both our identity and our purpose: “But you are a chosen race, a royal priesthood, a holy nation, a people for his own possession, that you may proclaim the excellencies of him who called you out of darkness into his marvelous light” (1 Peter 2:9).
Peter says this definitively. There is zero question who the Christians are. They are a chosen race. A royal priesthood. A holy nation. A people for his own possession. That identity is written in stone. Because of that, Christians’ purpose is to proclaim the excellencies of him who called them from darkness into his marvelous light. We all were sinners, lost and driven by our dark ways. But now we entered the saving light of Jesus our Savior.
This guides our actions and determines how we treat others. Paul said, “But now that you have been set free from sin and have become slaves of God, the fruit you get leads to sanctification and its end, eternal life. For the wages of sin is death, but the free gift of God is eternal life in Christ Jesus our Lord” (Romans 6:22). Our identity now is in Christ, and in him alone. We belong to him. We’ve entered his light and now proclaim the excellencies of him who called us from darkness into that light!
