The most famous star in the history is the one which led the Magi to find our Savior, Jesus Christ. Although we say it is the most famous, but actually no one knows what kind of star it is, and its name. Someone may guess it may be a comet; when it came near to the earth and produced a special effect, and sent out bright shiny glory light. Perhaps this may be true.
However, I think that the Christians should also act as that star, guiding people to look for the Savior.They do not care about their own status or their fame, but are only proud of to be a Christian.
Obviously, St. Paul absolutely agreed with me, he talked to the faithful, "among whom you shine like lights in the world." ( Philippians 2:15)
