'Existed' in the Bible

What existed from the beginning, what we have heard, what we have seen with our eyes, what we observed and touched with our own hands this is the Word of life!

and the Life [an aspect of His being] was manifested, and we have seen [it as eyewitnesses] and testify and declare to you [the Life], the eternal Life who was [already existing] with the Father and was [actually] made visible to us [His followers]—

I am writing to you, fathers, because you have known the one who has existed from the beginning. I am writing to you, young people, because you have overcome the evil one.

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.
