V 26. As for Philip, an angel of the Lord said to him, “Go southdown the desert road that runs from Jerusalem to Gaza.” So he started out, and he met the treasurer of Ethiopia,
There’s no knowing what God might ask you to do! Philip was a great witness for Jesus – he’d been to many towns talking about Jesus, and now God gets him to change direction in order to meet up with one single traveller. So off he goes, from town to desert, and the Ethiopian Treasurer hears about Jesus before returning to his own country. How else could the church in East Africa have started without the obedience of Philip? Then Philip gets back to speaking in various towns right up to Caesarea.
It seems that Philip settled in Caesarea and was visited at a later date by Paul, recorded in Acts 21:8. ‘ The next day we went on to Caesarea and stayed at the home of Philip the Evangelist, one of the seven men who had been chosen to distribute food. He had four unmarried daughters who had the gift of prophecy.’
Even then he was referred to as Philip the Evangelist, the same Philip that introduced Nathanael to Jesus (John 1:45) and also introduced some Greek travellers to Him. (John 12:21)
It seems that Philip had this reputation of meeting people and introducing them to Jesus. That after all, is what Mission is all about.
