You might meet an angel. That is what Lot did in that passage in Genesis and they escaped the destruction of Sodom. Abraham and Sarah entertained three strangers who were really angels. There are lots of stories of people who had encounters with strangers who helped them in unusual circumstances and then disappeared. Mission fields are filled with these stories.
Angels are real, folks.
They walk among us disguised as human beings. You never know if a stranger who comes to church one Sunday is really an angel come to enjoy our worship and fellowship. You may have your own angel stories. Angels are real. There are myriads of angels.
