Trust as the ultimate form of love?

Andrea asked me last night what I liked the most about being married. This had every feeling of being a trap. Of course I thought a bit before I blurted out, "The Sex!". Then instead I said it was a great question, squirming as I wanted to appear romantic and spiritual. 

The answers all seemed to obvious. Sex, sharing life, kids... As I thought more on the question over my New Orleans pasta, (Duncan Creek Wine Bar & Grill in Chippewa). The thing I appreciate the most about being married is the trust. The trust is what allows for great sex and physical intimacy. Its trust that allows for a physical union where one plus one equals in our case five or nine.  Its trust that fosters the wanting to share the best and worst parts of who we are. 

My question is; is this the kind of love God has for us? Is free will and the entrusting of that gift, (what ever form you believe in), the ultimate form of divine love?  If so what have you done with this love and how do you reflect this to the ones you love?
