Passage
The Elder to Gaius the beloved, whom I love in truth!
The Elder to Gaius the beloved, whom I love in truth!
3 John 1:1 The Elder to Gaius the beloved, whom I love in truth!
3 John 1:2 beloved, concerning all things I desire thee to prosper, and to be in health, even as thy soul doth prosper,
3 John 1:3 for I rejoiced exceedingly, brethren coming and testifying of the truth in thee, even as thou in truth dost walk;
The verse centers on "elder", "gaius", "beloved", and "truth". It is saying that the verse draws attention to "elder" and "gaius", so its meaning should be read from those terms before moving to application.
The next verse adds "beloved concerning all things I desire thee...", so "elder" and "gaius" should be read forward into that movement. In 3 John context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "elder" and "gaius" with trust shaped by these words, not by a vague optimism outside the passage.
