1 John 3
10 Ref In 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.
11 Ref Because this is the word which was given to you from the first, that we are to have love for one another;
12 Ref Not 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.
13 Ref Do not be surprised, my brothers, if the world has no love for you.
14 Ref We 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.
