7 Brethren, I write no new commandement vnto you, but an olde commandement which ye had from the beginning: the old commandement is the word which ye haue heard from the beginning.
8 Againe, a new commandement I write vnto you, which thing is true in him and in you: because the darkenesse is past, and the true light now shineth.
9 He that saith he is in the light, and hateth his brother, is in darkenesse euen vntill now.
10 Hee that loueth his brother, abideth in the light, and there is none occasion of stumbling in him.
11 But he that hateth his brother, is in darknesse, and walketh in darknesse, and knoweth not whither hee goeth, because that darknesse hath blinded his eyes.
12 I write vnto you, little children, because your sinnes are forgiuen you for his Names sake.
13 I write vnto you, fathers, because yee haue knowen him that is from the beginning. I write vnto you, young men, because you haue ouercome the wicked one. I write vnto you, little children, because yee haue knowen the Father.
14 I haue written vnto you, fathers, because ye haue knowen him that is from the beginning. I haue written vnto you, young men, because yee are strong, and the word of God abideth in you, and yee haue ouercome the wicked one.
15 Loue not the world, neither the things that are in the world. If any man loue the world, the loue of the Father is not in him.
16 For all that is in the world, the lust of the flesh, the lust of the eyes, and the pride of life, is not of the Father, but is of the world.
17 And the world passeth away, and the lust thereof, but hee that doeth the will of God, abideth for euer.
