1 John 2:11 Meaning

9He that saith he is in the light, and hateth his brother, is in darkness even until now.

10He that loveth his brother abideth in the light, and there is none occasion of stumbling in him.

11But he that hateth his brother is in darkness, and walketh in darkness, and knoweth not whither he goeth, because that darkness hath blinded his eyes.

12I write unto you, little children, because your sins are forgiven you for his name's sake.

13I write unto you, fathers, because ye have known him that is from the beginning. I write unto you, young men, because ye have overcome the wicked one. I write unto you, little children, because ye have known the Father.
