1 John 3:10-20

10 In this thing the sons of God be known, and the sons of the fiend. Each man that is not just, is not of God, and he that loveth not his brother [and he that loveth not his brother, is not of God].

11 For this is the telling, that ye heard at the beginning, that ye love each other;

12 not as Cain, that was of the devil, and slew his brother. And for what thing slew he him? for his works were evil, and his brother's just.

13 Brethren, do not ye wonder, if the world hateth you.

14 We know, that we be translated from death to life, for we love brethren. He that loveth not, dwelleth in death.

15 Each man that hateth his brother, is a manslayer; and ye know, that each manslayer hath not everlasting life dwelling in him.

16 In this thing we have known the charity of God, for he put his life for us, and we owe to put our lives for our brethren.

17 He that hath the chattel of this world, and seeth that his brother hath need [He that shall have the substance of this world, and shall see his brother have need], and closeth his entrails from him, how dwelleth the charity of God in him?

18 My little sons, love we not in word, neither in tongue, but in work and truth.

19 In this thing we know, that we be of truth, and in his sight we admonish our hearts.

20 For if our heart reprove us, God is more than our heart, and knoweth all things.
