Man and woman were created to be physically attracted to each other, irrespective of their looks, stature, color, or other qualities that differentiate one person from another. What causes attraction between the opposite sex is in-built in man (man and woman) from creation. This is why couples fall in love with each other and later get married - just as it was intended by God, the Creator. However, "many couples fall in love, marry, and assume that the job is completed. They believe that everything else will work out automatically." This is far from the truth. A successful relationship does not come by chance. It has to be worked for in love by the couples concerned.
