and the Life was manifested, and we have seen, and do testify, and declare to you the Life, the age-during, which was with the Father, and was manifested to us --

and this is the testimony, that life age-during did God give to us, and this -- the life -- is in His Son;

he who is having the Son, hath the life; he who is not having the Son of God -- the life he hath not.
