Rev. Rodimer, I'm touched.
I agree John 3:16 isn't a verse we should be promoting at sporting events. It's a great verse, don't get me wrong, but when it's all by itself it does tend to promote a very wrong interpretation of Christianity.
I think something along the lines of Revelation 21:8 would be a good verse to promote. It just seems to capture everything True Christianity™ is about.
"But the fearful, and unbelieving, and the abominable, and murderers, and whoremongers, and sorcerers, and idolaters, and all liars, shall have their part in the lake which burneth with fire and brimstone: which is the second death." Revelation 21:8
