To seek God together you must pray together. Sure, it can be awkward to pray together at first, but consider this: it's hard to pray with someone you're mad at. It's harder to want a divorce from someone you're praying with. It's even more difficult to have an affair when you're seeking God together.
Talk: What things in your marriage do you want to bring before God in prayer?
Pray: Pray about those things you discussed with your spouse about your marriage.
Do: Make a list of things you prayed about. Keep this list in a place where it will remind you to pray together. Feel free to add to your list as things come to mind.
