Anyone can say, “I love God,” yet have hatred toward another believer. This makes him a phony, because if you don’t love a brother or sister, whom you can see, how can you truly love God, whom you can’t see?
But whoever hates a fellow believer lives in the darkness—stumbling around in the dark with no clue where he is going, for he is blinded by the darkness.
But if anyone lacks these things, he is blind, constantly closing his eyes to the mysteries of our faith, and forgetting his innocence—for his past sins have been washed away.
Here is how God’s children can be clearly distinguished from the children of the Evil One. Anyone who does not demonstrate righteousness and show love to fellow believers is not living with God as his source.
