We live in a secular society. One can no longer assume that the average person we meet knows the language or symbols of our faith.
A friend of mine went to a mall department store not long ago to purchase a cross necklace for his wife. When he asked the clerk to show him the various options being offered for sale, she responded with a curious question: "Do you want a cross with or without a little man on it?"
The only thing the clerk knew was that some people preferred a crucifix (Catholics) and others like the image of the empty cross (Protestants). The "little man" the clerk was referring to, of course, was Jesus of Nazareth!
There was a time when everyone in America, including people from other religions, knew something about Jesus. That can no longer be assumed.
If you are a person of faith, don't assume people understand about Jesus. They probably do not know about him so it is our privilege and responsibility to tell them.
