HOW SHOULD HUSBANDS AND WIVES TREAT EACH OTHER?

For in this way in former times the holy women, who hoped in God, used to adorn themselves, being submissive to their own husbands and adapting themselves to them;
I Peter 3:5 (AMP)

just as Sarah obeyed Abraham (following him and having regard for him as head of their house), calling him lord. And you have become her daughters if you do what is right without being frightened by any fear (that is, being respectful toward your husband but not giving in to intimidation, nor allowing yourself to be lead into sin, nor to be harmed).
I Peter 3:6 (AMP)

In the same way, you husbands, live with your wives in an understanding way (with great gentleness and tact, and with an intelligent regard for the marriage relationship), as with someone physically weaker, since she is a woman. Show her honor and respect as a fellow heir of the grace of life, so that your prayers will not be hindered or ineffective.
I Peter 3:7 (AMP)

Out of respect for Christ, be courteously reverent to one another.
Ephesians 5:21 (MSG)

Wives, understand and support your husbands in ways that show your support for Christ. The husband provides leadership to his wife the way Christ does to His church, not by domineering but by cherishing. So just as the church submits to Christ, as he exercises such leadership, wives should likewise submit to their husbands.
Ephesians 5:21-24 (MSG)

Husbands, go all out in your love for your wives, exactly as Christ did for the church, a love marked by giving, not getting. Christ’s love makes the church whole. His words evoke her beauty. Everything He does and says is designed to bring the best out of her, dressing her in dazzling white silk, radiant with holiness. And that is how husbands ought to love their wives. They’re really doing themselves a favor, since they’re already “one” in marriage.
Ephesians 5:25-28 (MSG)

No one abuses his own body, does he? No, he feeds and pampers it. That’s how Christ treats us, the church, since we are part of His body. And this is why a man leaves father and mother and cherishes his wife. No longer two, they become “one flesh”. This a huge mystery, and I don’t pretend to understand it all. What is clearest to me is the way Christ treats the church. And this provides a good picture of how each husband is to treat his wife, loving himself in loving her, and how each wife is to honor her husband.
Ephesians 5:29-33 (MSG)
