Im not sure being in the moment is the point to life. Actually there is no justification for life in general. From what I understand, humans make up stuff to deal with existence so the uncertainty of existing doesn't make us feel that it's entirely hopless. Hence the social narrative that people buy into in the name of a long life that we have no real justification for.
thanks for the reply
I’m not saying it is the point to life, though our time is now, might apply. And the truth is, as you say, there is no justification for a long or short length of days in the world, other than, it was given to be in the world.
Living is done in vain, by those who believe living is done in vain. To give of life is fruits of life that is never done in vain even if the giving is to the thankless, and the ungrateful. If life is given to the believer, then Life is righteous because all men women and children are capable of believing, no other qualification necessary, even to those that believe living is done in vain. And all have the present, or now, to believe.
