It’s very good to have friendship in your marriage and to experience a strong attraction and sexual relationship with your spouse. I believe most marriages have at least some of both. But Christ’s love for the church goes beyond this level of love. His love is a giving, sacrificing, selfless love. It is a love that shows itself in action.
“But God demonstrates his own love for us in this: While we were still sinners, Christ died for us.” Romans 5:8
Jesus loved and gave, not because we were attractive or shared some interest with him, but simply because he loved us. So he humbled himself, he gave up all his glory to serve us. This is the way we are to love our husbands or wives: Giving ourselves, dying to self, serving our spouse.
