If you are a Christian, and within Christianity yes still applies/should apply.
But like so many other stuff in the WATCHTOWER CORPORATION and other cults, they use these scriptures to promote a "sick" respect for men/husbands among us women. For some JW's wive this "respect" turns them into emotional, physical, sexual abuse VICTIMS, which is not the intended spirit of that biblical advice.
Now that I am a Christian, and believe that the Holy Spirit helps me to understand bible principles, I can apply these to my everyday life and I am way happier than ever. I am re-married and I love and respect my husband, but the respect that I now have for him comes from the admiration I have for him. We encourage each other to be better persons, friends, parents, neighbors, Christians, volunteers, citizens, etc... we encourage each other to get ahead in life, set goals for the future, take care of our health and bodies/appearance, we cheered each other's accomplishments and yield to each other knowing that we BOTH are children of the MOST HIGH GOD. I think that we both have a "healthy" view of the biblical commands when it comes to the relationship of husband and wife, but don't get me wrong, we are very casual, spontaneous, "young" contemporary traditionals, everybody always comments on how much fun we always have with each other (and our children sick - lol), and trust me, it is not a "show" - it comes naturally but part of it is because we are so happy to be spiritual and emotional free and we regard each other as children of God, not slaves or servants, but CHILDREN of our Heavenly Father. This makes a huge difference in the way you put into practice a lot of biblical principles - of course Watchtower CORPORATION and other cults puts you into a sick "slave", "servant" relationship with God thus that relationship causes "pain," as it is a heavy yoke on you. God through the bible tells us that his commandments should result in benefits, happiness, joy, life for us and most of all should glorify HIM - so if you are not feeling this or the results do not glorify God and your results are not a light for others ... you getting pears from an apple tree, something is out of line.
As long as another person, cult CORPORATION, tells you how to live the biblical commands, what they mean, how to apply them in your life as if they were God, if it is not the Spirit within you leading/teaching/reaveling you, I think it will always result in "death" so to say. The biblical commands are to be lived in the Spirit and to accomplish this one has to be born again of the Spirit, you cannot be applying/living spiritual concepts in the flesh, you have to be "in the Spirit." As believers, followers of Jesus Christ, our realm is the Spiritual realm, spiritually speaking we are not of this world of flesh. Oil and water don't mix. Biblical advice which it is intended to be lived in the Spirit to produce its fruit, cannot be lived in the flesh. Of course the benefits can be seen in the flesh, but cannot be accomplish or obtain in the flesh, for this you have the Spiritual. One has to believe you are in a covenant relationship of Father/Child with God.
But the natural man receiveth not the things of the Spirit of God: for they are foolishness unto him: neither can he know them, because they are spiritually discerned" (1st Corinthians 2:14).
