Different Minds by Richard Chenevix Trench.

SOME murmur when

their sky is clear
And wholly bright to view,
If one small speck of dark appear
In their great heaven of blue;
And some with thankful love are filled
If but one streak of light,
One ray of God’s good mercy, gild
The darkness of their night.

In palaces are hearts that ask,
In discontent and pride,
Why life is such a dreary task,
And all good things denied;
And hearts in poorest huts admire
How Love has in their aid
(Love that not ever seems to tire)
Such rich provision made.
