Though I have many things to write to you, I do not want to do so with paper and ink; but I hope to come to you and speak face to face, so that your joy may be made full. [2 John 12]
In our modern society, there are many applications we can use to keep in contact with our loved ones eg email, facebook, video conferencing and instant messaging. John felt that the best mode of communications was to meet and talk face to face. That would be joyful for all parties. Perhaps we should learn from him.
