A life not of this world.
Marine fish life, I think, is very interesting to contemplate. They hatch, grow big, play, swim, and breed in salty sea water. Amazingly, their meat does not become salty. We can enjoy it as a healthy and delicious meal. That's it. The environment is not able to influence them. Salty environment does not necessarily make their bodies salty. So everyone has to believe and believe that something good when in life does not have to drift with the flow of life of this world. Why? Because we still have a life that is not from this world.
