Just because it was necessary doesn’t mean that it always will be. In fact, this concept is in a constant flux and flow and nothing is necessary forever. For example, I stink, and I feel dull, so a shower is necessary to lift my spirit and remove the stench. But once I have showered it is not necessary any longer, because it has been done and I am clean. It is a very simple metaphor but when I phrase and view it like this, it is so easy to see. That “all things have its time, and things are necessary until they are not anymore”. Not even breathing. Only as long as we are still here in this body and flesh. But once we transcend, not even that is necessary.
