Marriage is a financial venture and the husband has a responsibility to finance, support, AND provide for his family. This is talking about money. As a husband your earnings are not your own, but belong to your wife as well and your children. Another responsibility of the husband is to be active in the area of the discipline and rearing of the children. Now this discipline should be with love.
Many times discipline is administered without love.
The husband therefore does not leave all the discipline up to his wife, but shares in the molding and direction of HIS children. The Christian father should set an example for his family as he earns a living, directs the household with concern for each member, and as he fulfills his role as head of the house. He should see to their spiritual development by the life he lives and the direction in which he leads his family. Your wife is a part of your body - you are a part of each other. He didn't say, if you want to.
