I am writing to you, little children, because your sins are forgiven for his sake. I am writing to you, fathers, because you know him who is from the beginning. I am writing to you, young men, because you have overcome the evil one. I write to you, children, because you know the Father. I write to you, fathers, because you know him who is from the beginning. I write to you, young men, because you are strong, and the word of God abides in you, and you have overcome the evil one.
Do not love the world or the things in the world. If any one loves the world, love for the Father is not in him. For all that is in the world, the lust of the flesh and the lust of the eyes and the pride of life, is not of the Father but is of the world. And the world passes away, and the lust of it; but he who does the will of God abides for ever.
–1 John 2:12-17
