With the rise of Humanism during the Renaissance, societies began turning away from God's laws and God's ways. From the Enlightenment sprang a virtual worship of nature. Once nature, not God, became the standard for morality, people started believing that, since humans are a mere product of nature, anything we do naturally is normal, and even good. Sex is natural, sex is powerful, and so it eventually followed that sexual expression was seen as a natural and normal part of all human existence in any circumstances, much on the level of eating and sleeping. Given the sexually charged atmosphere in which we live, it is not surprising that so many people are having sex outside of marriage and getting pregnant.
Some women get pregnant because of someone else's sin.
The Bible's View of the Unborn Historically, hiding the evidence of sexual activity was the main reason for abortions. They maintain that no one really knows when human life begins, and they choose to believe that the idea of personhood at conception is a religious tenet and therefore not valid. It is a human life that is formed at conception. The zygote contains 46 chromosomes, half contributed by each parent, in a unique configuration that has never existed before and never will again. It is not plant life or animal life, nor is it mere tissue like a tumor.
