What husbands and wives owe each other

From the “Table of Duties” in Luther’s SMALL CATECHISM:

HUSBANDS
Likewise you husbands, dwell with them with understanding, giving honor to the wife, as to the weaker vessel, and as being heirs together of the grace of life, that your prayers not be hindered. 1 Peter 3:7.
Husbands, love your wives and do not be bitter toward them. Colossians 3:19.
 
WIVES
Wives, submit yourselves to your own husbands, as to the Lord…as Sarah obeyed Abraham, calling him lord, whose daughters you are as long as you do good and are not afraid with any terror. Ephesians 5:22; 1 Peter 3:6.

So wives love and serve their husbands by submitting to them, as to Christ; and husbands love and serve their wives by giving themselves up for their wives, as Christ did for the church.

It is surely easier for the wife to submit to her husband if he is giving himself up for her.

Notice that Christ is in marriage. And both husbands and wives bear a cross of self-sacrifice for the other.
