United hearts, seeking God's perfect will together, is the very best way for your relationships to grow closer to each other, as well as closer to God as a couple. People will always have times of growth as Individuals. Couples have times of growth through unity... unity in travel plans, purchase plans, unity in plans for raising children, and so much more. The best way is ALWAYS GOD'S WAY. The only way for any of us to know God's way is to spend time with Him in Scripture study and prayer.
