In Acts 2 we see the pouring out of the Holy Spirit upon the Church on the day of Pentecost. In this event, we learn that 1) The Spirit is the powerful presence of God to empower His church; 2) The Spirit enables the communication of the Gospel to all people; and 3) The Spirit democratizes the knowledge of God. In Peter’s sermon we see his proclamation of the Gospel and his appeal to his listeners to respond in faith and repentance.
