1 John 1:2-4

Amplified Bible

² 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]— ³ what we have seen and heard we also proclaim to you, so that you too may have fellowship [as partners] with us. And indeed our fellowship [which is a distinguishing mark of born-again believers] is with the Father, and with His Son Jesus Christ. ⁴ We are writing these things to you so that our joy [in seeing you included] may be made complete [by having you share in the joy of salvation].
