Communication is vital in a relationship. I know that a lot of the problems we encounter in marriage life is the result of poor communication. One statement I remember that I liked from class is the fact that no one, not even our spouses can read our minds. God can. But only him. And I think this is why it's so important to include him in our lives, to counsel with him on a day to day bases; because he understands us better.
I also liked what we about with verbal and non-verbal language. How we used symbols and methods of communicating simple things. That's the way our Heavenly Father communicates to us, in fact many times, it's through personal feelings and the warmth in our inner-person that we recognize his communication.
