But you shall receive power when the Holy Spirit has come upon you; and you shall be witnesses to Me in Jerusalem, and in all Judea and Samaria, and to the end of the earth (Acts 1:8).
Empowered by the Holy Spirit, the Apostles obeyed the Great Commission of Jesus by preaching in the city of Jerusalem, then in Judea and Samaria, finally to the far reaches of the Roman world.
The Jewish people – and remember the Apostles were Jews – believed that God was only interested in them, the physical descendants of Abraham. The first controversy in Christianity was whether or not a person could even be a Christian apart from Judaism; but Jesus was actually the Saviour of the world, not just the Jews (Rom 10:12; Gal 3:28; 1 John 4:14).
On the Jewish holy day of Pentecost, the Holy Spirit came upon the disciples, empowering them to preach as eye-witnesses to the death and resurrection of Jesus (Acts 1-2). From Jerusalem, the Apostles fanned out to preach about Jesus in Judea and Samaria, the Jewish regions surrounding Jerusalem.
In the Samarian city of Caesarea, the Apostle Peter visited the home of a Roman military commander named Cornelius. As he preached Jesus, the Holy Spirit came upon those who heard the gospel, just as happened in Jerusalem. Peter testified that God gave them the same gift as He gave us when we believed on the Lord Jesus Christ … God has also granted to the Gentiles repentance to life (Acts 11:17, 18).
Shortly after that, the Apostle Paul took the Gospel outside of Israel to the Gentiles. When Paul preached in Ephesus, the most important Greek city in the world at the time of the New Testament, the Holy Spirit came upon the hearers just as He’d done in Jerusalem and Caesarea.
This Pentecostal experience was only ever repeated twice: once in the house of a Roman solider in Samaria, and among a group of Gentiles in the Greek city of Ephesus. The Pentecostal experience proved to the Apostles that the Gospel wasn’t meant for the Jews alone but Jesus is the Saviour for as many as the Lord our God will call (Acts 2:39).
There is no more Pentecostal experience: the Gospel has gone out to the ends of the earth and the Church knows that Jesus saves Jews and Gentiles alike.
