Adriana and I just finished reading The Love Dare by Stephen Kendrick and Alex Kendrick. It can be done by each spouse individually and then discussed together as a couple, but we took the route of reading each lesson together before bed. Though as seasoned Christians none of the lessons were incredibly profound, they were nonetheless great, simple reminders that caused us to reflect on ourselves as individuals and on our relationship together as a couple. It was a great, marriage-strengthening, bonding time that we really enjoyed together. I would highly recommend the book as a worthy investment. It would also make a great gift for newlyweds.
