I marveled at the goodness and awesomeness of our Creator! And I recalled the psalmist praising God with these beautiful words: "You formed my inmost being; you knit me in my mother's womb. I praise you, because I am wonderfully made; wonderful are your works!"
Just think of the awesomeness of how human life comes into existence. According to Medline Plus of the U.S. National Library of Medicine (see: http://1.usa.gov/1WRK2rF), when a single male sperm and the mother's egg unite conception occurs. This new single cell known as a zygote contains all of the genetic information (DNA) needed for the new human being to develop throughout life.
Just think about it: Your life started as a single cell zygote. And now look at you!
At around four days, the zygote now consisting of 32 cells becomes known as an embryo. During the next seven and half weeks the human embryo develops all of the body's systems and structures.
According to Alexander Tsiaras, image-maker, mathematician and associate professor of medicine at Yale University, at four weeks in utero the human heart is growing at an astounding rate of 1 million cells per second.
From the eighth week after conception, the baby is known as a fetus. At this point of development, organs like the brain, liver and kidneys start functioning inside the tiny human life. Life support systems continue growing and becoming ever more sophisticated until the baby is able to live outside the mother's protective and nurturing womb.
