In the book of Revelation, we find we are reading someone else’s mail. Jesus sent a message through John to specific churches in Asia Minor. But the Spirit has preserved these words to speak to us still today!
The community of Jesus followers in Philadelphia was small and had little power. They had been displaced from their home by earthquakes and even when they were able to go back and rebuild, they were caught between two opposing powers; the Greco-Roman worship of gods and Caesar, and the Jewish synagogue who wouldn’t let Jesus followers in. This small church is one of two out of the seven that Jesus had nothing to say against, but only words of encouragement, hope, and a promise for those who endure.
