Peter preached Christ crucified and risen. As a result, thousands were convicted of their sin and need for salvation. They repented, placing their trust and being baptized in the name of Jesus. Their response was more than emotional as evidenced by a whole new orbit of life, centered in a persistent devotion to Christ—together. Luke closes this foundational chapter with a summary of the newly formed Christian church. Vitals of the church in its thriving infancy are highlighted to remind us of the essentials. Every detail testifies that the redeemed, by design, thrive together for Christ.
