Tenants Rights for the Unborn: Women have the right to control their OWN bodies but unborn babies are not organs.
Likewise, women have the right to control their own bodies. However, whenever they engage in sexual intercourse with a man, the couple is jointly signing a lease agreement to provide for and protect any babies (tenants) that come about as the result of that sexual activity for at least 18 years and 9 months. If couples realized that every time they have sex, they are essentially posting an advertisement on Craigslist that says, "Womb for Rent", I'm sure they would make better choices about when, with whom, and under what circumstances (preferably in a good marriage) that they had sexual intercourse.
Sometimes people ask, "doesn't the woman have the right to control her own body?" My answer is absolutely, "Yes!" The woman has the right to decide whether or not to post the, "womb for rent" advertisement or not. Furthermore, the woman has the right to remove any organ that belongs to HER OWN body (shares 100% of her DNA). But, science has proven that the unborn baby DOES NOT have the same DNA and many times does not even have the same blood type as the mother. Therefore the Baby is not part of the mother's body and therefore she does not have the right to kill or injure it before birth any more than a father would have the right to kill or injure his child after birth.
Therefore the unborn baby is a tenant of her womb and therefore cannot be evicted unjustly and certainly cannot be killed. Now some may mention rape or incest. In this case, the woman did not agree to lease her womb to the baby so the unborn baby could be seen as a squatter or an illegal immigrant. Landlords have the right to evict squatters and governments can deport illegal immigrants but they still do not have the right to kill or injure them. In this case, the closest equivalent to evicting a squatter would be to adopt the baby out after birth, which would avoid killing or injuring the baby but would free the mother from the rest of the 18 years commitment to support and care for her offspring. Barrier methods of contraception would still be permitted because they serve to discourage tenants from renting the property (like high rent prices) but there is always a chance that some tenant will overcome those barriers. Once they are in "residency" the landowners options are limited and all tenants and even squatters deserve basic protections as human beings (they should not be killed or injured). The unborn babies should not be treated worse than tenants or even squatters and illegal immigrants.
The analogy above is sufficient reason why abortion is morally unjustifiable but those of us who are born-again Christians (see John 3) are held to an even higher standard. 1 Corinthians 6:19-20 says, "Don’t you realize that your body is the temple of the Holy Spirit, who lives in you and was given to you by God? You do not belong to yourself, for God bought you with a high price. So you must honor God with your body." So for Christians, we are not even the landlords of our own lives and bodies because we belong to Jesus Christ. In other words, we are only property managers and so we can only manage our lives and bodies according to the wishes of the true owner, Jesus Christ.
Biblically, abortion is a serious sin. But the Good News is that Jesus Christ died to pay for all of our sins, including abortion. Romans 8:1-2 says, "So now there is no condemnation for those who belong to Christ Jesus. And because you belong to him, the power of the life-giving Spirit has freed you from the power of sin that leads to death." This is Good News indeed!
