Acts 4 (verses 1–12) recounts Peter’s bold defense before the Jewish leaders after healing a crippled man. Filled with the Holy Spirit, Peter declares that the miracle occurred by Jesus Christ—whom they crucified and whom God raised—calling Jesus the rejected stone now become the cornerstone and insisting there is no other name for salvation. The sermon connects Old Testament prophecy, the resurrection’s cosmic significance, and the resulting clash between Christ’s kingdom and earthly authorities.
