Ephesians 5:25; Ephesians 5:29-32
And you husbands must love your wives with the same love Christ showed the church. He gave up his life for her
No one hates his own body but lovingly cares for it, just as Christ cares for his body, which is the church.
And we are his body.
As the Scriptures say, "A man leaves his father and mother and is joined to his wife, and the two are united into one."
This is a great mystery, but it is an illustration of the way Christ and the church are one.
