Many things in the world can press in and keep couples from praying together. Making a commitment to shared prayer, then keeping it can bring spiritual intimacy to your marriage. Making prayer a top priority can make a marriage vital as you share common concerns and joy in prayerful conversation with God.
Many couples have so many time constraints that they find it hard to find a time to pray.
Later, work at extending the time. We like doing things different ways. Some couples have different styles and expectations for prayer and devotions. One may like praying at a regular time each day while the other likes spontaneous prayer. These two styles can sabotage each other when trying to set a time to pray together.
