How does Peter describe Jesus in his sermon?

In his sermon, Peter describes Jesus as a living stone, chosen by God and precious to believers. This metaphor illustrates not only Christ's foundational role in the church but also His eternal presence and sustenance for His people. Peter emphasizes that despite being rejected by men, Jesus holds supreme value and importance for those who have come to know Him. This preciousness is inherent in His sacrificial role as the Redeemer, essential for the salvation and spiritual nourishment of His followers, as echoed in verses dedicated to his worthiness and the sufficiency of His atoning death.
