If you have life, then the Creator gave it to you. If he gave it to you, then no lesser being can take it from you. This is the right to life.
This right is further confirmed by the Creator's law that no one should murder. You therefore have the right to defend your life.
This is sovereignty on the earthly, horizontal plane (between men); but we have no sovereignty on the vertical plane (between man and his Creator) -- because He alone is sovereign in that relationship.
