For it was you who formed my inward parts; you knit me together in my mother’s womb. I praise you, for I am fearfully and wonderfully made. Wonderful are your works; that I know very well. My frame was not hidden from you, when I was being made in secret, intricately woven in the depths of the earth. Your eyes beheld my unformed substance. In your book were written all the days that were formed for me, when none of them as yet existed.
(Psalms 139:13-16)

On the contrary, the parts of the body which seem to be weaker are indispensable, and those parts of the body which we think less honorable we invest with the greater honor, and our unpresentable parts are treated with greater modesty, which our more presentable parts do not require. But God has so composed the body, giving the greater honor to the inferior part… (1 Corinthians 12:22-24)
Bless the LORD, O my soul; and all that is within me, bless his holy name! (Psalms 103:1)
St Cyril of Jerusalem writes:
Look within yourself. From your own nature you can learn something of your Maker.
There is nothing to be ashamed of in your body. If you are in control of its members, they are not in the slightest evil. Adam and Eve in paradise were naked at first and their bodies did not appear shameful or disgusting. Our limbs do not cause sin, but the wrong use of them does. The Creator of our bodies knew what he was doing.
Who makes the secret parts of the mother’s womb able to bear children? Who gives life to the lifeless fruit of conception? Who shapes the sinews and bones, who covers all with flesh and skin? When the baby comes to the light, who gives the milk that it can suck? How does the newborn infant grow to become a child, then an adolescent, then an adult, and then in the end an old person?
Who imposes on the heart the regularity of its beat? Who protects so skilfully our eyes with their eyelashes? Who makes our whole bodies able to be kept alive by our breathing?
Look at your Maker. Admire your wise Creator. The greatness and the beauty of his creatures will help you to contemplate him.
