John 13:35- “By this everyone will know that you are my disciples, if you love one another.” 
A horseshoe, a four-lear clover, and a wishbone. Each symbolizes good luck.
Manufacturers have unique symbols for their products, whether they be cars, shoes, clothing, or eyeglasses.
Sports teams and schools choose mascots to make themselves more recognizable to the public and to build team/school spirit.
Traffic signs utilize symbols to help drivers become instantly aware of the rules of the road, especially those involving emergencies/warnings.
One interesting symbol Christians sometimes use is that of the fish, often seen on fenders, jewelry, and stationary.
The use of the fish symbol by Christians began in the early days of Christianity. Since Christians were often put to death for practicing their faith, they often worshiped in secret places.
A fish painted on the outside door of a house let Christians know that they would be safe and welcome inside. It was also used as a Christian greeting. Upon meeting someone new, a believer would draw half of the fish symbol in the dirt and the other person (if a Christian) would complete the other half of the symbol, thus revealing himself or herself as a Christian.
However, if the other person did not recognize what was being drawn, he was most likely a non-believer. Thus, the believers’s religious beliefs remained hidden.
Today, the Christian fish symbol is often used to identify Christians and/or Christian businesses. Free from persecution, at least here in the United States, the fish symbol is proudly displayed for all to see.
Jesus tells us that it is not symbols, elaborate robes, or showy prayers that should identify Christians to the world.
He wants us to show love and understanding to each other… to grant others the same mercy and grace he extended to us.
They will know we are Christians by our love.
