'Eternal Life' in the Bible

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]—

Everyone who hates (works against) his brother [in Christ] is [at heart] a murderer [by God’s standards]; and you know that no murderer has eternal life abiding in him.

And the testimony is this: God has given us eternal life [we already possess it], and this life is in His Son [resulting in our spiritual completeness, and eternal companionship with Him].

These things I have written to you who believe in the name of the Son of God [which represents all that Jesus Christ is and does], so that you will know [with settled and absolute knowledge] that you [already] have eternal life.
