'Existed' in the Bible

I am writing to you, fathers, because you know Him who has existed from the very beginning. I am writing to you, young men, because you have overcome the Evil one. I have written to you, children, because you know the Father.

I have written to you, fathers, because you know Him who has existed from the very beginning. I have written to you, young men, because you are strong and God's Message still has a place in your hearts, and you have overcome the Evil one.
