If you look at vs.2 you will see the reference to it being well with my soul. I love this song and not just because my daughter sings it with such passion and it brings a tear to my eyes almost every time we sing it. It also reflects what John is saying to his community. No matter what is happening in our life and in our world. It is well with our soul.
Paul calls a couple people out by name, one in a negative way and one in a positive way. Diotrephes takes part in ministry just to build himself up. Demetrius works for the church and the people of the church. John wraps up this third letter by telling the church that he can’t wait to see them face to face.
This isn’t the end of John, we hear from him again in Revelation. I can’t wait!
