Robert William Service - Ommission

What man has not betrayed
Some sacred trust?
If haply you are made
Of honest dust,
Vaunt not of glory due,
Of triumph won:
Think, think of duties you
Have left undone.

But if in mercy hope,
Despite your sin,
The gates of Heaven ope'
To let you in:
Pray, pray that when God reads
Your judgement due,
He may forget good deeds
You did not do.

Ommission sins may be
The bitterest,
And wring in memory
A heart opprest;
So when sweet pity pleads,
Let us not rue
Too late, too late Kind Deeds
We did not do.

Robert William Service
