The Last Days Begin
In the Book of Acts , the application of Joel’s prophecy to the events of the Day of Pentecost links the outpouring of the Spirit on the Church to the start of the “ Last Days .” The activity of the Spirit beginning that day is essential for understanding the rapid spread of the Gospel from Jerusalem to the center of the Roman Empire. That same process must continue until the “ arrival ” or ‘ Parousia ’ of Jesus at the end of the present age.
