A fetus is the joining of a sperm and egg to create a human being. After that has taken place the growing of an embryo inside of a woman is a live organism that if left alone will become a full-grown human being. To just decide you don't want to have a baby because it is inconvenient is wrong from my point of view. When you ask this question to some Christians they will say, "Well if a woman decides she doesn't want to have the baby it's her right to abort the baby," but I disagree with that. I think that once a person becomes pregnant then they should have the baby. If they don't want to raise the baby there are plenty of couples who are looking for babies to adopt. As we become more sophisticated and can harvest organs to do cosmetic things - to me that would be unethical and unrighteous and unholy because you're taking that which has the life of God and making it into a commercial product or using it for a way that might not be bringing the greatest glory to God. We as human beings are made to bring glory and honor to God.
