In 1936 an advertising executive in Philadelphia, Philip Klein, founded the Friday the 13th Club. Its members are committed to defying old superstitions. They walk under ladders. They break mirrors. The sit at a table set for thirteen. Two American Presidents, Herbert Hoover and Franklin D. Roosevelt, wouldn't sit a table set for thirteen! So far no member of the club has experienced any bad results.
But there are people who fear the number 13. That fear is called
triskaidekaphobia. It's common enough that most hotels do not have a 13th
floor. Of course, such fears are groundless and have no foundation in fact. Our
faith should keep us from such fears. God is in charge of this world and there
really is no such thing as luck, good or bad.
