The power of God is redefined in Jesus as practical costly service extending to those who are beyond the normal boundaries of human concern: the diseased, the poor, the oppressed, the outcast. If humans are to claim a lordship over creation, then it can only be a lordship of service. There can be no lordship without service. According to the theological doctrine of animal rights, then, humans are to be the servant species — the species given power, opportunity, and privilege to give themselves, nay sacrifice themselves, for the weaker, suffering creatures.
