John 3:16. If you ask just about anyone in America if they can quote a Bible verse (regardless of whether or not they're a Christian), chances are, this is the verse that pops into their head- and for good reason! "For God so loved the world that He gave His only begotten Son, so that whosoever believes in Him shall have everlasting life." It's the epitome of the Gospel crunched into one simple promise.
According to Wikipedia...
The phrase "John 3:16" is very short and can be written inconspicuously in out-of-the-way locations. In the U.S., the In-N-Out Burger chain prints it on the inside of the bottom rim of their paper cups, clothing chain Forever 21 and Heritage (1981) print it on the bottom of their shopping bags, and Tornado Fuel Saver prints it on the box.
Some people display the reference in large letters at sporting events, seeking the attention of fellow fans, the staff controlling the venue's giant video screens and, if the game is televised, the television audience.
The Heisman-winning American football player Tim Tebow printed this reference (among other Bible verses) on his eye black, notably during the 2009 BCS championship. Exactly three years later on January 8, 2012, was the game that would become known as "The 3:16 game", where Tebow threw for 316 yards in a playoff upset against the Pittsburgh Steelers; a game in which measurements of 3, 16 and 31.6 were also noted, "John 3 16" became the top Google search in the US
