I know now what I'm about to say will be very controversial, but I also believe that God's greatest gift is human life and that we have a sacred duty to protect the innocent human life of an unborn child. Now I realize that this view is not shared by all. But out of all the debate on this subject has come one undisputed fact, and this, out of the debate, has been the uncertainty of when life begins. And I just happen to believe that simple morality dictates that unless and until someone can prove the unborn human is not alive, we must give it the benefit of the doubt and assume it is. And thus it should be entitled to life, liberty, and the pursuit of happiness.
