Everyone knows the Gospel of John 3:16, which adorns countless tee-shirts and signs, especially at sporting events. We wont go into here the idea that it is probably a much later addition to the text. What is not so often remembered are the Epistles of John, almost certainly a different author.
As an exercise, I decided to look up the John 3:17s in the texts, and in First Epistle of John 3:17 I found this:
“If anyone has material possession and sees his brother in need, but has no pity on him, how can the love of God be in him?”
I must say, its a shame that THAT never finds its way onto a tee-shirt.
