This is totally awesome and fuck all the haters!
Have you SEEN "Whoomp! Praise the Lord?" That's a cringeworthy parody - this is just funny!
The redone lyrics are actually creative and funny, unlike 90% of all parodies, secular or otherwise. And the people are obviously not taking it too seriously and have a good sense of humor about music AND religion. Go them!
Come on, the chorus is "NIV with a ribbon bookmark," what's not to love!
