Today 3 John finishes remarkably similarly to 2 John.
13 I had much to write to you, but I would rather not write with pen and ink.
14 I hope to see you soon, and we will talk face to face.
15 Peace be to you. The friends greet you. Greet the friends, each by name.
Now here’s 2 John,
12 Though I have much to write to you, I would rather not use paper and ink. Instead I hope to come to you and talk face to face, so that our joy may be complete.
13 The children of your elect sister greet you.
Both speak of John having much to write, both tell us of his desire to not write with pen and ink.
3 John 1.14 is the perfect ending to this letter about living out the truth of Jesus personally, because personal truth always wants to connect with other personal truth.
So, simply, when we profess and possess the truth of Jesus, this will ALWAYS result in the desire to spend time with others who have professed and possessed.
Preaching through Hebrews we phrased it like this –
There is no true heart change and decision for Jesus that results in the desire to NOT be with other believers.

Simply, followers desire fellowship.

John then finishes with a familiar blessing in Scripture, for which we have the resources in Jesus. He writes, peace be to you, and again, the truth of Jesus lived out in our lives brings true and lasting peace (John 16.33, John 14.27, Galatians 5.22).
3 John shows us how the truth of Jesus looks in our individual lives, and this ending shows us how we are to interact and talk to others; face to face, with peace, and as friends.
Point to ponder – Do my interactions look like this?
Prayer – Father, we thank you that despite this letter being short it speaks to us in powerful ways. Help us to live the truth of Jesus both collectively as believers, and individually too. Amen.
