Could/Would/Should

Here stands the good:
The Right; The Light; The Should;
The Love Which Is The Law.
Still, you demand
a more clear command,
More strength for the race,
More graces for grace.
"You would, but you can't."
But here is the truth absent cant:
The truth without slant:

You could -
if you would.
But, you dont?
Because... because?
Because, you pause:
You dont because you won't.

You may -
there's a way.
But you stay; you delay,
and pray (so you say)
for a better time and day.

The now is the how;
The true is to do;
The act is the fact.
