Summary: The child within this women's womb (Prahlad Maharaj) is faultless and sinless. He is a great devotee, a powerful servant of the Supreme Personality of Godhead, therefore you will not be able to kill him. The Lord sent a protector for this child, which was just going to be aborted. There have been many instances in which demons or non-devotees have attempted to kill a devotee, but they never have been able to destroy a great devotee of the Supreme Personality of Godhead. The Lord promises in the Bhagavad gita that His devotee cannot be killed by demons.
