人若说自己在光明中。却恨他的弟兄，他到如今还是在黑暗里。爱弟兄的就是住在光明中，在他并没有绊跌的缘由。惟独恨弟兄的是在黑暗里，且在黑暗里行，也不知道往哪里去，因为黑暗叫他眼睛瞎了。
Whoever says he is in the light and hates his brother is still in darkness. Whoever loves his brother abides in the light, and in him there is no cause for stumbling. But whoever hates his brother is in the darkness and walks in the darkness, and does not know where he is going, because the darkness has blinded his eyes. (ESV)
