Do you regularly read and/or study the Bible with your wife?
I know some men are shy about discussing spiritual matters, sometimes especially so with their wife. It’s a deeply private thing for many of us, sometimes even more private than our sexuality. And yet, much like our sexuality, our view of and experience with God is a deeply foundational part of who we are. If we hide the deepest parts of ourself, how can we know and be known?
If you have limited discussion of the Bible with your bride, I encourage you to make a change. Start slowly and build gradually.
