Classic Poem

MY God , how perfect are thy ways!
But mine polluted are;
Sin twines itself about my praise,
And slides into my pray'r.

When I would speak what thou hast done
To save me from my sin,
I cannot make thy mercies known
But self-applause creeps in.

Divine desire, that holy flame
Thy grace creates in me;
Alas! impatience is its name,
When it returns to thee.

This heart, a fountain of vile thoughts,
How does it overflow?
While self upon the surface floats
Still bubbling from below.

Let others in the gaudy dress
Of fancied merit shine;
The L ORD shall be my righteousness;
The L ORD for ever mine.
