Recall from our reading of Genesis 2:18-23 that God created the woman to be a helper suitable to the man. Man was not designed by God to live a life of isolation. He needs a companion and a friend.
In Titus 2:4-5, older women are asked to teach younger women how to love their husbands. The word for love in this passage comes from the Greek word phillio. It is the love shown between best friends. You would think that this would come naturally to any wife, but Paul said it needs to be taught.
It is not what you can get out of a marriage that is important, but what you put into it. Jesus said it is more blessed to give than to receive (Acts 20:35). The concept of giving goes beyond monetary aid. It reflects the Christian attitude of service to others. The husband brings to the relationship his devotion to his wife and his wife gives him the companionship he needs.
