Does Your Marriage Strengthen Your Faith?

I think the idea that a shared faith life can strengthen your marriage is pretty common, but I've been musing about the reverse:

Do you intentionally look to your marriage as a "platform" from which you pursue your faith? Put another way, is your primary life partner your primary faith partner?

I came to this from a curious direction. I think a lot about small groups and house churches. More recently I encountered suggestions for "Three is Enough" groups as well as "Church of Two." One thing that seemed to be in common across all of these is that you have to begin by finding one or more people to team up with, and then spend some time building a significant relationship of trust. With that foundation established, you can work together to pursue your faith with support, encouragement and sharing of ideas, insights etc.

Eventually, I wondered why not start with an established relationship of trust that a great many of us already have in place: our spouse? And I'm not talking here about sharing a life of faith as a way to strengthen the marriage, though it certainly will. Rather, the focus is on intentionally turning to the marriage relationship as a resource for pursuing faith. After all, there we hopefully already have someone who knows us well enough to "speak into our life" as they say. Hopefully, with enough trust built up to be able to "speak (and hear) the truth in love." And generally, someone you can get quality time with fairly easily (even though we often don't.)

Wouldn't that be easier than trying to find someone, find a place and time to meet, and start building a deep, faith-based relationship?

I'd love to hear from others who have though about this, or better yet begun to live that way. What have your experiences been? What kind of practices have you found helpful (or not.) What challenges have you encountered?
