Which as I have proven (to the deafening sound of numerous FWer crickets) that the world is not used in the distributive sense in scripture since Israel was never part of the world, anymore than Gentile Christians are. See my posts 27,679, 27,725 and 27,934. The text above does not say, "but also for the rest of the world". Or "but also for the remainder of the world". The John excluded himself and his original audience from the world. There are "our sins" and the sins of "the whole world".
... John wrote that to the CHURCH!
