The king of Egypt said to the Hebrew midwives, whose names were Shiphrah and Puah, “When you are helping the Hebrew women during childbirth on the delivery stool, if you see that the baby is a boy, kill him; but if it is a girl, let her live.” The midwives, however, feared God and did not do what the king of Egypt had told them to do; they let the boys live. Then the king of Egypt summoned the midwives and asked them, “Why have you done this? Why have you let the boys live?”
The midwives answered Pharaoh, “Hebrew women are not like Egyptian women; they are vigorous and give birth before the midwives arrive.”
There aren't any explicit references to abortion in the bible. Nevertheless God obviously knew that it would be a common thing in the future and he has provided enough reason from the bible to say that it is sinful and evil.So God was kind to the midwives and the people increased and became even more numerous. And because the midwives feared God, he gave them families of their own.
What we see in the verses above is one reference that supports the pro-life campaign. Pharaoh ordered that all the Israelite boys be killed, but that the girls be allowed to live. The two midwives who he commanded to do this disobeyed him, and God blessed them for it.
There is absolutely no difference between a baby when it is in the womb and when it is born. Biologically nothing changes between those two points in time: it still is human, with the same DNA. Mentally the baby is the same as well. It also relies on the mother just as much before birth as afterward. The only thing that changes is the physical location of that child and if it is not aborted then it would grow to be a man or woman with thoughts, opinions, likes, dislikes and feelings. Babies are human, as are foetuses, as are adults.
God blesses these women for preserving the life of these children, even though it would have been inconvenient and even dangerous for them. He blesses them. That means he agrees with what they did. Children are a blessing from God - don't kill them before they have a chance to live.
Abortion is evil and it is sinful. Don't get me wrong - we all sin. We all stuff up. Those who have had an abortion are no worse then anyone else: we all deserve God's wrath (hell) eternally. But that isn't an excuse to keep sinning. It's a reason to come running to Jesus who offers forgiveness, to repent and to change. To follow him instead of living our own ways.
If you've had an abortion, then repent of it and turn to God - he will forgive.
Just stop the killing.
