'Written' in the Bible

I have written to you, children, that you have known the Father. I have written to you, fathers, that you have known him who has been from the beginning. I have written to you, young people, that you are strong, and the word of God resides in you, and you have conquered the evil one.

I have not written to you that you do not know the truth, but that you do know it, and that no lie is of the truth.

These things I have written to you about those who are trying to deceive you.

I have written these things to you who believe in the name of the Son of God so that you may know that you have eternal life.
