A Debtor to Grace Alone

I stumbled across the lyrics to this 18th Century Hymn tonight. It's amazing:

A Debtor to Mercy Alone
Agustus Toplady 1740

A debtor to mercy alone,
Of covenant mercy I sing
Nor fear, with Thy righteousness on
My person and offering to bring.
The terrors of law and of God,
With me can have nothing to do.
My Savior’s obedience and blood
Hide all my transgressions from view.

The work which His goodness began
The arm of His strength will complete.
His promise is yea and amen,
And never was forfeited yet.
Things future, nor things that are now,
Not all things below nor above
Can make Him His purpose forego,
Or sever my soul from His love.

My name from the palms of His hands
Eternity will not erase
Impressed on His heart it remains
In marks of indelible grace.
Yes, I to the end shall endure
As sure as the earnest is given
More happy but not more secure
The glorified spirits in heaven.

Yes, I to the end shall endure
As sure as the earnest is given
More happy but not more secure
The glorified spirits in heaven.
