Some good verses to see this in are Ephesians 5:21-33 and Colossians 3:18-19
This Momentary Marriage by John Piper is an excellent book showing the beautiful picture marriage was created by God to be.
Pretty much all the great pastors and authors that I have been largely influenced by use pen and ink primarily for their deep studying. That is, a pen which must be dipped into the ink (as the older authors had to do) or a fountain pen which must be regularly refilled with ink (as the modern ones do). I thought it was just a weird notion of theirs that these actually make a difference when writing and studying. I was wrong. Something got into me one day and I tried one. This is no weird notion. It changes the whole way of writing, it affects the brain, it allows a person to have a deeper relationship with what they are authoring. I know, it sounds crazy. But don't be too quick to call me crazy until you try one! As I was pursuing the art of using fountain pens, I ran out of ink and had to buy myself a real genuine ink bottle. In old books you read about the ink on a writer's finger. You also read about the mess this ink can make. Well, just so you know, it's true.
