Christian worldview core beliefs that are relevant to this scenario are thou shall not kill, humans have souls, God instructed us to be fruitful and multiply, and humanity is created in God's image. It is against God's law to abort a child. Thou shall not kill. God instructed humanity to be fruitful and multiply and abortion violates many of God's requests. God loves everyone and does not care if they are intellectually challenged or not. God does not make mistakes. It was his will for Susan to be pregnant and it is God's will for Susan to have the baby. Whether Susan keeps the baby or gives it to a loving family is Susan's choice, but taking the life of an individual because they are intellectually disabled is not the Christian thing to do. Abortion is murder and God has a zero tolerance policy when it comes to murder. We are all created in the image of God. Just because one has a "defect" does not make them any less Godlike. Human life starts at conception and depends upon the presence of the soul.
