Analysis of Olney Hymn 51: Lively Hope And Gracious Fear

I was a grovelling creature once,
And basely cleaved to earth:
I wanted spirit to renounce
The clod that gave me birth.

But God hath breathed upon a worm,
And sent me from above
Wings such as clothe an angel's form,
The wings of joy and love.

With these to Pisgah's top I fly
And there delighted stand,
To view, beneath a shining sky,
The spacious promised land.

The Lord of all the vast domain
Has promised it to me,
The length and breadth of all the plain
As far as faith can see.

How glorious is my privilege!
To Thee for help I call;
I stand upon a mountain's edge,
O save me, lest I fall!

Though much exalted in the Lord,
My strength is not my own;
Then let me tremble at His word,
And none shall cast me down.
