Act - The Working of the Holy Spirit by Stephen Kaung and published by Christian Fellowship Publishers.
On the day of Pentecost following the resurrection of Christ and His ascension back to the Father in heaven, the Holy Spirit fell upon the 120 of Christ's followers who were gathered together in the upper room of a house in Jerusalem, resulting in the formation of the body of Christ and the birth of the church. And these Spirit-filled believers immediately began to glorify God and to testify concerning the Lord Jesus. Furthermore, through their testimony 3,000 more souls were added to the church on that very same day. All this marked the beginning of the church of God on earth.
