My husband and I are also both Christians-we actually met in youth group and "saved" ourselves for each other until we were married. My how our ideologies have changed! But at the core, we both still identify as Christian, especially my husband. I am constantly reminded that God is LOVE-and that's what my life is about-loving others. Maybe a verse that can be of help to your husband is in I Corinthians 13:8 when it says that only love will remain.
