How to be demonstrative of positive?

I suggest gladness is an evocative,

And through a consequence of the causative;

a presence of your highest prerogative.

It’s rare to find care in a world of unfair.

Be aware of the pair of sharing and prayer,

and there will be air from the place where you stare;

it is fresh I declare, which nothing compares.

Though I am walking through the shadow’s valley,

I’ll steadfastly endure all my pain gladly,

while thanking exactly those who have grandly

made all this amply wondrous and happy.
