As they traveled along the road they came to some water, and the eunuch said, "Look, there is water. What is to prevent my being baptized?" Then he ordered the chariot to stop, and Philip and the eunuch both went down into the water, and he baptized him. (Acts 8:26-40)

The story of Philip and the Ethiopian Eunuch is probably one of the most important in the life of the early church. When the eunuch asks, “What is to prevent my being baptized?”, the answer of course is the Law of God, in which men like him were considered an abomination. Yet, it is the Spirit at work in Philip and in the eunuch, and so Philip baptizes him and the eunuch “continued on his way rejoicing.”
