Passage
The elder to the elect lady and her children, whom I love in truth, and not only I, but also all who know the truth,
The elder to the elect lady and her children, whom I love in truth, and not only I, but also all who know the truth,
2 John 1:1 The elder to the elect lady and her children, whom I love in truth, and not only I, but also all who know the truth,
2 John 1:2 for the sake of the truth which abides in us and will be with us forever:
2 John 1:3 Grace, mercy, and peace will be with us, from God the Father and from Jesus Christ, the Son of the Father, in truth and love.
The verse centers on "elder", "elect", "lady", "children", "love", "truth", and "only". It is saying that the verse draws attention to "elder" and "elect", so its meaning should be read from those terms before moving to application.
The next verse adds "for the sake of the truth which...", so "elder" and "elect" should be read forward into that movement. In 2 John context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "elder" and "elect" with trust shaped by these words, not by a vague optimism outside the passage.
