'Written' in the Bible

I have written to you, children, because you have known the Father. I have written to you, fathers, because you have known the [One who is] from the beginning. I have written to you, young men, because you are strong, and the word of God resides in you, and you have conquered the evil one.

I have not written to you because you do not know the truth, but because you do know it, and because every lie is not of the truth.

These [things] I have written to you concerning the ones who are trying to deceive you.

These [things] I have written to you who believe in the name of the Son of God, in order that you may know that you have eternal life.
