1 John 2:12-15

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. 14I have written unto you, fathers, because ye have known him that is from the beginning. I have written unto you, young men, because ye are strong, and the word of God abideth in you, and ye have overcome the wicked one.

15Love not the world, neither the things that are in the world. If any man love the world, the love of the Father is not in him.
