Classic Poem

Would it be loss or gain
To hapless human-kind
If we could feel no pain
Of body or of mind?
Would it be for our good
If we were calloused so,
And God in mercy should
End all our woe?
II
I wonder and I doubt:
It is my bright belief
We should be poor without
The gift of grief.
For suffering may be
A blessing, not a bane,
And though we sorrow we
Should praise for Pain.
III
Aye, it's my brave belief
That grateful we should be,
Since in the heart of grief
Is love and sympathy,
We do not weep in vain,
So let us kiss the rod,
And see in purging Pain
The Grace of God.
