Doggerel amuses me.
(Could someone not have had a word with William Cowper, the theologian par excellence, and suggested something more ...subtle in his rhyme?!).
Anyway, lay aside your dislike for rigid rhyme and delight in the essential truth that men like Newton wrote about. I like "The Kite". It exposes my self-admiration and impatience at God's providence.
Boy, do they need exposing.

Once on a time a paper kite
Was mounted to a wondrous height,
Where, giddy with its elevation,
It thus expressed self-admiration:

"See how the crowds of gazing people
Admire my flight above the steeple;
How would they wonder if they knew
All that a kite like me can do!

Were I but free, I'd take a flight,
And pierce the clouds beyond their sight,
But, ah! like a poor pris'ner bound,
My string confines me near the ground;

I'd brave the eagle's towering wing,
Might I but fly without a string."
It tugged and pull, while thus it spoke,
To break the string--at last it broke.

Deprived at once of all its stay,
In vain it tried to soar away;
Unable its own weight to bear,
It fluttered downward through the air;

Unable its own course to guide,
The winds soon plunged it in the tide.
Ah! foolish kite, thou hadst no wing,
How could'st thou fly without a string!

My heart replied, "O Lord, I see
How much this kite resembles me!
Forgetful that by thee I stand,
Impatient of thy ruling hand;
How oft I've wished to break the lines
Thy wisdom for my lot assigns?

How oft indulged a vain desire
For something more, or something higher?
And, but for grace and love divine,
A fall thus dreadful had been mine."

--John Newton
