10In this way it is clear who are the children of God and who are the children of the Evil One; anyone who does not do righteousness or who has no love for his brother, is not a child of God.
11Because this is the word which was given to you from the first, that we are to have love for one another;
12Not being of the Evil One like Cain, who put his brother to death. And why did he put him to death? Because his works were evil and his brother's works were good.
13Do not be surprised, my brothers, if the world has no love for you.
14We are conscious that we have come out of death into life because of our love for the brothers. He who has no love is still in death.
15Anyone who has hate for his brother is a taker of life, and you may be certain that no taker of life has eternal life in him.
16In this we see what love is, because he gave his life for us; and it is right for us to give our lives for the brothers.
