He extended the primary text (Acts 2:1-13) to include elements of Peter’s sermon (vv. 16-21, quoting Joel the prophet) and drew an interesting connection with John the Baptist’s words, recorded in Matthew 3:11-12:
I indeed baptize you with water unto repentance, but He who is coming after me is mightier than I, whose sandals I am not worthy to carry. He will baptize you with the Holy Spirit and fire. His winnowing fan is in His hand, and He will thoroughly clean out His threshing floor, and gather wheat into the barn; but He will burn up the chaff with unquenchable fire.Pentecost was the Jewish feast of celebration for the wheat harvest. On the first Pentecost after Jesus’ resurrection and ascension, the Holy Spirit descended upon the disciples in Jerusalem, evidenced by their speaking in tongues and proclaiming God’s mighty works in the languages of people gathered from distant lands. We typically understand this event to be the “birthday” of the church, setting the stage for the inclusion of Gentile believers in God’s household of faith.
The point Kyle added to this understanding was the element of judgment. He touched upon the fact that, for centuries, Christians have speculated on whether they were living in the “last days.” Citing other New Testament texts (particularly Hebrews 1:2 and 1 John 2:18) he asserted that we are indeed in the last days, and have been so since the day of Pentecost. As the spirit of Anti-Christ has gone out into the world, so has the Holy Spirit, convicting the world of sin, righteousness, and judgment.
The people assembled in Jerusalem that Pentecost were faced with a decision. Those who believed on Jesus were gathered like wheat for the barn. Those who resisted were separated as chaff prepared for fire.
The threshing floor has been swept clean continually down to our time.
