Ephesians 5:29-31

After all, no one ever hated his own body, but he feeds and cares for it, just as Christ does the church—

(v29, NIV)

Husbands are to love their wives as their own bodies. By loving their wives, they love themselves. It would only make sense, since why would anyone hate his own body? We live and breathe and eat, feeding our own body. We take care of our body; or at least we should take care of our body. We are to take care of our own body as Christ does the church. Our wives are part of our own bodies, so husbands take care of your wives as you would your own body.

for we are members of his body. "For this reason a man will leave his father and mother and be united to his wife, and the two will become one flesh."

(v30-31, NIV)

We, the church, are members of his body. Jesus takes care of his own body, and we are part of that body. You may think that Jesus is doing something completely different than what husbands are called to do for their wives. Husbands and wives come together to become one flesh, but one may object that Jesus is not one flesh with the church. However, we the church, are members of his body.
