As they traveled along the road, they came to some water and the eunuch said, “Look, here is water. What can stand in the way of my being baptized?” And he gave orders to stop the chariot. Then both Philip and the eunuch went down into the water and Philip baptized him. – Acts 8:36-38 (NIV)

Philip is instructed by an angel of the Lord to travel a desert road between Jerusalem and Gaza. While traveling he encounters an Ethiopian eunuch who was reading aloud from the prophet Isaiah (chapter 53:7-8). Through the Spirit’s guidance Philip teaches the eunuch about Jesus, the suffering servant in whom Isaiah prophesies.
