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.
15 Whoever hates his brother is a murderer: and you know that no murderer has eternal life abiding in him.
16 Hereby perceive we the love of God, because he laid down his life for us: and we ought to lay down our lives for the brothers.
17 But whoever has this world's good, and sees his brother have need, and shuts up his bowels of compassion from him, how dwells the love of God in him?
18 My little children, let us not love in word, neither in tongue; but in deed and in truth.
