Philip
Acts 6, 8
Philip is known for carrying the Gospel to the marginalized Samaritans. He preached in the city of Samaria to large crowds. But the Holy Spirit led him out into the wilderness to preach to a single person—an Ethiopian eunuch. This man was reading the book of Isaiah as he traveled, but he did not understand what he was reading. Philip showed him from the Scriptures how he could be saved.
After leading the Ethiopian to the Lord and baptizing him, Philip continued on his trip to the coast and eventually to the city of Caesarea. He stayed in Caesarea and established a church there.
