Philip is directed by the angel of the Lord to leave the revival in Samaria and go to a desert place.  As he obeys the command, Philip encounters a high-ranking official from Ethiopia.  The Spirit of God directed him to engage the Ethiopian and the man invited Philip to join him and explain the scriptures.  Upon believing, the eunuch requested to be baptized.  Philip discerned that the Ethiopian's faith was sincere and he baptized him.  Coming out of the water, the Spirit caught away Philip and he continued preaching on his way to Caesarea.  The Ethiopian returned home with true joy!
