Acts 8:25-40 It seems that Philip traveled back towards Jerusalem with Peter and John, but somewhere along the way an angel spoke to him, telling him to take the desert road to Gaza. Gaza was located south west of Jerusalem, towards the Mediterranean Sea. The Lord led Philip to meet an Ethiopian court official along the road. This man worked directly for the queen of Ethiopia called Candace. He was in charge of all of the queen's treasure, and "he had come to Jerusalem to worship."
The man had procured a copy of the scroll of Isaiah and was reading it aloud as he traveled by carriage or chariot along the road. The Holy Spirit told Philip to catch up to the carriage and so he ran along the road and heard the man reading. He asked him, "Do you understand what you are reading?"
Well it just so happened that he was reading Isaiah 53 which is the Messianic prophecy about Jesus being "led as a sheep to slaughter". The man wondered if this was Isaiah talking about himself or someone else and Philip "preached Jesus to him." Whatever scriptures Philip used we are not told.. how long they talked we do not know.. but it was enough that the man ordered the chariot to stop when they came across some water and he asked to be baptized!
Philip spoke again " If you believe with all your heart, you may" The man testified clearly, " I believe that Jesus Christ is the Son of God." Then Philip baptized him right then and there! The man went his way rejoicing.. but Philip was swept away by the Spirit and found himself in another town, Azotus ( Ashdod) miles away.
Philip just kept walking north along the sea, stopping at city after city "preaching the gospel". He ended up in Caesarea. Caesarea was an important city because it was the place that Herod the Great had built. It had a great harbor where Paul would sail from and it was the place of his trial before Felix, Festus, and Agrippa. The city had a majority of Greek citizens.
It appears that Philip established a church there in Caesarea.. In Acts 21:8 we are told that Paul and his team stayed with Philip on his way to Jerusalem. Philip had "four virgin daughters who were prophetesses". It was at that time that Agabus, another prophet from Judea, came and took Paul's belt and tied up his own feet and hands to demonstrate what was going to happen when Paul went to Jerusalem. The church wept for Paul and begged him not to go.. but Paul knew that he had to anyway. There were disciples from this church that accompanied Paul to Jerusalem. Some of these may have been the Greeks that were seen with Paul and thought to have been brought into the temple.. leading to Paul's arrest.
Father in heaven, thank You for men like Philip and Paul and others who preached Jesus! May godly men and women, filled by Your Spirit, moved by Your Spirit, and even swept away by Your Spirit.. continue to preach Jesus wherever they go! Fill us today, that we might hear Your voice and find those who You are sending us to.. and tell them about Jesus Christ. Bless Your servants today Lord God. We ask this in Jesus' name. Amen.
