In this passage, Peter reminds believers that they are being built into a spiritual house, with Christ as the cornerstone—chosen by God but rejected by men. As living stones, Christians are called to be a holy priesthood, offering spiritual sacrifices acceptable to God through Jesus. Though some reject Christ and stumble, those who believe in Him are honored and will never be put to shame. Peter emphasizes that believers are a chosen people, a royal priesthood, and a holy nation, called to proclaim the goodness of God who brought them from darkness into light. Once far from God, they are now His people, recipients of His mercy.
