God's greatest power is that of conferring life, sentient life. We might have imagined that that marvelous power he would have kept for Himself alone, but He has not done so. We have also the power to confer life. We can call into existence other human beings, and endow them with the record of our own lives, giving to them our form, our features, our measure of vitality, our tendencies, our habits; and these human beings whom we have thus called into life will never die. What diviner, more responsible gift could God have conferred upon us than this? What more worthy of our devout study? In this reverent attitude of mind let us study this gift of creative power, learning what we may of its scope and purpose and the material organs through which it works. In your study of physiology in school you took up the organs of individual life. You studied the framework of the body, its machinery, its internal vital mechanism. You studied about digestion, nutrition, respiration, elimination, and in this you learned nothing of physical differences between individuals. All were considered as having the same organs, used in the same way. Girls have the same number of bones as boys, the same number of muscles, of vital organs. They sleep, breathe, eat, digest, grow, according to the same plan. So far there seems no reason why there should be any distinction of male and female. But as we come to study what is called special physiology we discover physical differences and reasons for their existence. There are certain differences of form that are discernible at a glance. Men are usually larger than women. They have heavier bones and bigger muscles. They have broad shoulders and narrow hips, and have hair upon the face. Women have smooth faces, more rounded outlines, narrower shoulders and broader hips. In man the broadest part of the body is at the shoulders, in woman at the hips. This is significant of a great fact which will be manifest to you when you understand the functions of each sex. Although each has the same general plan of individual life, there are special functions which determine the trend of their lives. The man's broad shoulders are indicative that he is to bear the heavy burdens of life--struggles for material support--and woman's broad hips indicate that she is to bear the heavier burden of the race. When we come fully to understand the deep significance of sex, we shall find in it a wonderful revelation of possibilities of development into a God-likeness that will stir our hearts to their very depths. Humanity so weak, so lacking in appreciation of his possibilities, so groveling when he should soar, has been endowed with powers that give him control over the destiny of the race. We may well exclaim, with Young:
