Passage
I have no greater joy than this, to hear about my children walking in truth.
I have no greater joy than this, to hear about my children walking in truth.
3 John 1:2 Beloved, I pray that you may prosper in all things and be healthy, even as your soul prospers.
3 John 1:3 For I rejoiced greatly, when brothers came and testified about your truth, even as you walk in truth.
3 John 1:4 I have no greater joy than this, to hear about my children walking in truth.
3 John 1:5 Beloved, you do a faithful work in whatever you accomplish for those who are brothers and strangers.
3 John 1:6 They have testified about your love before the assembly. You will do well to send them forward on their journey in a way worthy of God,
The verse centers on "greater", "than", "hear", "children", "walking", and "truth". It is saying that the verse draws attention to "greater" and "than", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 3's "For I rejoiced greatly when brothers came..." into verse 5's "Beloved you do a faithful work in...", so "greater" and "than" belong inside that flow. In 3 John context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "greater" and "than" with trust shaped by these words, not by a vague optimism outside the passage.
