Acts 2:1-2 (NKJV) When the Day of Pentecost had fully come, they were all with one accord in one place. 2 And suddenly there came a sound from heaven, as of a rushing mighty wind, and it filled the whole house where they were sitting.
The coming of the Holy Spirit on the Day of Pentecost was the fulfillment of Pentecost. Pentecost takes place fifty days after the Feast of Firstfruits which speaks of the resurrection of the Lord Jesus Christ for Christ is the firstufruits. As we are told in 1 Corinthians 15:23 (NKJV) which says “But each one in his own order: Christ the firstfruits, afterward those who are Christ’s at His coming.” The Passover speaks of the death of our Lord and Savior Jesus Christ, as we have learned from 1 Corinthians 5:7 (NKJV) which says, “Therefore purge out the old leaven, that you may be a new lump, since you truly are unleavened. For indeed Christ, our Passover, was sacrificed for us.” We believe that the Passover has been fulfilled in the death of the Lord Jesus Christ. We also believe that the Feast of Firstfruits has been fulfilled in the resurrection of Christ. And we believe that the Feast of Pentecost has been fulfilled by the birth of the church with the filling of the Holy Spirit of a group of people for a particular ministry to form the body of Christ which is the church. When these people gathered on the Day of Pentecost there was no church. But after the Holy Spirit came on the Day of Pentecost there was a church. The Holy Spirit baptized these believers, meaning that the Holy Spirit identified these believers with Christ as His body here on earth. And even today, the Holy Spirit baptizes believers into the body of Christ. “For by one Spirit we were all baptized into one body—whether Jews or Greeks, whether slaves or free—and have all been made to drink into one Spirit” (1 Corinthians 12:13 NKJV). “When the Day of Pentecost had fully come” means that Pentecost was fulfilled with the coming of the Holy Spirit. The coming of the Holy Spirit involved a sound to hear, a sight to see and a miracle to experience. That is how the Holy Spirit began His ministry on the Day of Pentecost, and He continues it today. The Holy Spirit is still baptizing believers into the body of Christ, which is the church.
God Bless and have a great day in God’s Word.
