'Written' in the Bible

I have written to you, little children, because you have known the Father. I have written to you, fathers, because you have known the one who has existed from the beginning. I have written to you, young people, because you are strong and because God's word remains in you and you have overcome the evil one.

I have not written to you because you do not know the truth, but because you do know it and because lies don't come from truth.

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.
