gifts of the Holy Spirit
The day of Pentecost and the city of Jerusalem set the stage for Acts 2. All that there was of Judaism was symbolizied in the city and the temple. The church had its beginninig in Jerusalem because its roots were in the types, shadows, prophecies, and promises of the OT.
The coming of the Spirit upon the apostles brought the question, "What meaneth this?" (Acts 2:12). Peter's sermon is in response to this question. Read the chapter carefully and notice that Peter uaed one of their question thruout his sermon.
1. And when "this" sound was heard Acts 2:16
2. What meaneth "this" Acts 2:12
3. Be "this" known unto you Acts 2:14
4. "This" is that Acts 2:16
5. He hath poured forth "this" Acts 2:33
6. Now when they heard "this" Acts 2:37
The chapter can almost be outlined around the word "this." In response to their question Peter quoted the propecy of Joel which is the key to the outpouring of the Spirit on the apostles. It also includes the miraculous gifts that would be imparted by the laying on of the apostles hands this is clear from the mention of "sons and daughters, young and old, servants and handmaidens." The statement of Joel is a summary of the miraculous during the infancy of the church. Keep iin mind when Peter quotes Joel he is responding to the question in verse 12, but Joel's prophecy extends beyond what the apostles received. It also includes Cornelius and the miraculous gifts received by the laying on of the apostles hands. All this is the sum of the miraculous work of the Spirit from Pentecost until revelation was completed and comfirmed. All this is summarized in the prophecy of Joel.
Since Peter was explaining Joel's prophecy, and the prophecy included spritual gifts through the laying on of the apostle's hands, would it not be resonable to conclude that Peter's promise of the gift of the Holy Spirit would be what the prophecy promised? Joel's prophecy has nothing to do with the non-miraculous. Why would Peter quote a prophecy having to do only with the miraculous and then conclude by promising a non-miraculous gift without any explanation?
