Loving your spouse and delighting in your spouse are two different things, and the difference, I think, is the difference between a good and a great marriage.
We all love lots of people, but we don’t delight in all those people.
To delight in someone means “to take great pleasure in them, to adore them, to revel in, luxuriate in.”
You can love someone and not delight in them.
To delight in your spouse means to look for ways to build them up, to help them accomplish goals and dreams, to help them succeed.
To delight means more than just fighting for purity in your marriage. It means delighting in purity in your marriage and holding up your love and purity for your spouse so that everyone around you knows and feels it. Here’s what I mean. Have you ever seen a couple who has been married 10, 15, 20+ years who is still holding hands, snuggling in public or sharing kisses? Pursuing each other outside of the bedroom, in front of people? This is delight.
Have you seen a couple who speaks highly of each other? When you hear the wife talk about her husband, how proud she is of him, how much he provides for her, the leadership he takes. At times you wonder if she is making stuff up, and she might be. But delighting in your spouse means seeing the person they are becoming and helping them to get there.
When we love someone, even at our best, we can often love them for what they give to us or how they fulfill us. Delight is different. Delight is a focus on the other.
