Kingdom Disciples

After completing his sermon, Peter summoned his audience to repent and be baptized “ in the name of Jesus Christ .” However, something more than just a call to accept the Gospel was transpiring in the passage. He concluded his sermon on a note of fulfillment and with a foretaste of things to come. It began with a citation from the Book of Joel , and it finished with a clause from the same passage, thus neatly bracketing the message.

The description of the outpouring of the Spirit on the Day of Pentecost stresses the theme of fulfillment. On that day, what was foreshadowed by the ancient feast began to receive its promised substance. The bestowal of the Spirit was an epochal event that marked the start of the Age of the Spirit, and the Gift of the Spirit fulfilled what the annual Levitical feast symbolized.

The use of Joel’s prophecy by Peter on the Day of Pentecost links the arrival of the Spirit to the start of History's final era. With the Spirit’s outpouring, the “ Last Days ” began in earnest.  The Gift of the Spirit is the “ Promise of Father ,” and an integral part of the  New Covenant  prophesied in the books of  Jeremiah  and  Ezekiel . Its arrival pointed to a fundamental change of eras - The time of fulfillment had commenced  - (Joel 2:28-32, Acts 2:17-21).

The prophecy in the book of Joel sets the tone for Acts, including the signs and wonders that accompany the gospel  – Acts 2:17-21.  Jesus told the disciples to “ tarry in Jerusalem ”  UNTIL  they receive the Spirit, then to proclaim the “ kingdom of God ” in Jerusalem, Judea, and Samaria, and the “ uttermost parts of the earth .” The book of  Acts  records how the early church carried out this mission under the power of the Spirit.

The final paragraph of the second chapter of Acts summarizes the results of the Spirit’s outpouring. It describes the basic practices of the young congregation that resulted from the Spirit’s presence – Teaching, shared meals, fellowship, prayers, unity, and material support for individuals in need. The one unique feature is the holding of possessions “in common” under the administration of the Apostles.

On Pentecost, the Spirit of God descended on the disciples accompanied by audible and visual manifestations. As they were “ filled with the Spirit ,” they all began “ speaking in other tongues .” This caused confusion and questions among the Jewish pilgrims who witnessed the epochal event.

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

In  Acts , the activity of the Spirit is essential to the life and growth of the church. The church was inaugurated by the outpouring of the Spirit on the day of Pentecost, and the young faith spread quickly from Judea to Samaria, Syria, Asia Minor, Greece, and finally, to the heart of the Roman Empire.

The book of  Acts  lays stress on fulfillment. The things foreshadowed in the Hebrew scriptures are actualized when the disciples are “ filled with the Spirit and spoke in other tongues ” on Pentecost. This is the seminal event that marks the inauguration of the Church, the age of the Spirit, and the commencement of the final harvest.
