AKJV(i)
10 In this the children of God are manifest, and the children of the devil: whoever does not righteousness is not of God, neither he that loves not his brother.
11 For this is the message that you heard from the beginning, that we should love one another.
12 Not as Cain, who was of that wicked one, and slew his brother. And why slew he him? Because his own works were evil, and his brother's righteous.
13 Marvel not, my brothers, if the world hate you.
14 We know that we have passed from death to life, because we love the brothers. He that loves not his brother stays in death.
