One of the most famous verses of all time is John 3:16,
"For God so loved the world, that he gave his only begotten son, that whoever believes in him would not perish but everlasting life."
This verse has been basically attached to what it means to be a Christian. The world has gotten numb to the verse, but this verse is the gospel. Well, we decided to make a design around it that was just weird enough that people would ask about it and not ignore it.
The book of John is the 43rd book in the bible. That is how we get 43 3 16. So when people ask about this design, just tell them about the gospel.
