It is difficult to explain the relation of bond between man and woman as one flesh in the marriage institution. But it is reasonable to know the main idea that the marriage was established by God. Many people do not know the purpose and the uniqueness of marriage. The solemnization of marriage is beyond calculation of anything that can be calculated. Marriage is beyond the world that can be called world or globe. If there is a world, then it is a marriage. If there is no marriage, then there is no world. In the beginning God created the Heavens and the Earth. The purpose of this world created by God was fulfilled by marriage. Yet, the marriage is the most honorable thing in the world than anything established by God. The world cannot be the world without marriage. It is a basic or source of human development which makes the world reasonable and necessary. So, the world became reasonable through human existence. It is a greatest sin to disregard marriage. The world was created for a man but it became necessary through marriage. The reason is that, it is not good for a man to live alone; yet, it is good for a man to have a partner or the helper fit for his life. The beauty is that, the man and the woman will be one flesh but not as different beings. This makes the reason of a marriage as it name meaningful and fruitful.
