The verse is a bit tangential and, on the other hand, not:

I strongly believe that caring about the life before the death is the most urgent task we have (which doesn't mean, considerations like in this thread are worthless). I do not believe in life after death but if I am mistaken I'm fairly confident that I shall be judged for what I have done regarding this life and not whether I already had a glimpse at afterlife. A person doing something good only with an eye to the eventual afterlife has my full contempt (I see no candidate here).

Wolf Biermann has made a record titled 'There is a life before death'. For him too, the 'task' we have is to make this life worth living (for us and others). The song is the title song of that recording where he tells, half mockingly and very serious, about the life after death, how comforting that belief is, for instance for him the good feeling that his father might still be somewhere though all what was left of him was a bit of smoke ascending from a chimney in Auschwitz (his father was a German Jew and a communist fighting in the underground against the Nazis each alone being already a sufficient reason for the Nazis to throw him into their killing machine).

But Biermann being critical of usual religion/religiousness (and in particular of the pie in the sky variant) ends the song with this last verse:

Ach (sigh), that there is something beautiful/good thereafter
is a solace in our situation.
How fine! But yet, there remains
the little, the big, the question
(and we'd love to know that as well)
whether there is such a thing - we'd love to have it -
a life even before our deaths.

Wolfgang
