" The disciples’ love is witness-bearing; it is missional communal theosis. It is how “everyone”—literally “all” (pantes)—will come to know that the disciples are disciples of Jesus (13:35; cf. 17:21–23). This could sound like a rather minimalist goal, conveying knowledge of identity. But far more is at stake. The disciples’ mutual love is necessary for an effective witness that ultimately points not to themselves, but to Jesus the Son and to God the Father, that is, to the One whose own love is the means and mode of the world’s salvation (cf. 17:20–26). The goal is for others to enter the eternal life that consists, not in knowing facts, but in knowing the Father and the Son (17:3). "
