If your spouse is open to it, pray together daily. If your spouse is not very spiritually motivated, then keep prayer very short and do it at a meal or another time that seems less intimidating. I know one couple who started praying together every day with the wife simply saying, “God, thank you for our food. Thank you for the children. Thank you so much for my husband. Help us to be a God-honoring couple and family. Amen.”
One day, after months of that prayer, my husband said, “Let me pray, too.” He said, “God, I’m not much of a pray-er but I agree with Karen, and thanks for Karen's heart for you. Amen, again!” After a while the kids got involved too. After a year we were feeling more comfortable praying together.
It is only when a husband and wife pray together before God that they find the secret of true harmony: that the difference in their temperaments, their ideas, and their tastes enriches their home instead of endangering it. When each of the marriage partners seeks quietly before God to see his own faults, recognizes his sin, and asks for the forgiveness of the other, marital problems are no more. They learn to become absolutely honest with each other. This is the price to be paid if partners very different from each other are to combine their gifts instead of setting them against each other.
Praying together can bring about spiritual intimacy and it can also restore a broken marriage. Praying together can strengthen a marriage that is lacking in communication and intimacy. It is certainly worth a try. The saying is true: “Couples who pray together, stay together.”
