Saving someone from destruction at one's own peril is as noble as it can possibly be. This nobility does not come from exploitation of peasants, grabbing land and getting rich at any costs. Nobility is not an aristocratic title, castles, receptions, elaborate balls.
True nobility is found in soldiers and firefighters because they lay their lives down on the line for others; they die for their country and for those in burning buildings.
But what are the origins of this sort of nobility for animals don't do it? Animals don't risk their own lives to save another. Therefore this instinct, if it can be called as such, comes with the human territory and its origin is indeed divine.
The one who created the Universe and this planet we call earth, has also established laws upon which the world stands. Why mankind needs saving and why this theme does not go away is hard to explain, and perhaps it shall never be satisfactorily explained. Things are as they are. But one thing for sure: man as a free agency upon this planet, having the free-will decides. How one uses this free agency determines the outcome. This outcome was not too good, nonetheless the Creator did not give up on His gone-astray creatures; He still seeks them and wants them to come back.
Looking after the needs of others; especially in cataclysmic situations is what the human spirit is all about. Salvation is the recurring theme that reverberates throughout human history.
Every living creature cares for its young. It is astounding to see that birds, fish and mammals care for their young as if having an emotion, but yet that instinctive emotion is also practical.
As it is among owls as long as the chick lives the mother will feed it, but when it dies the mother will eat it and share it with the her living chicks.
Humans have learned unprovoked and indiscriminate killing just to satisfy the cravings of their egos, which is an overbearing self-love; and this is hard to explain. Man gives no thought as to why he acts the way he does, so in this he is like any other animal that acts instinctively; while at the same time aspires to be different.
Whales nurture their young even though they starve endangering their own lives, yet they patiently wait until their calfs reach maturity. A long journey to the arctic seas is strewn with dangers like the predatory tactics of the Orca whales, so the calf must gain strength and reach the right size. The baby whale suckles on her mother's milk draining her of vital resources and in that state the mother attempts the journey with her calf. If she makes it and her calf survives the long swim the feast of plankton and small fish awaits them. This feasting prepares the whale for yet another cycle of life.
(44) But I say to you, love your enemies and pray for those who persecute you.
(46) For if you love those who love you, what reward do you have?
(47) If you greet only your brothers, what more are you doing than others? Do not even the Gentiles do the same?
(48) Therefore you are to be perfect, as your heavenly Father is perfect.
