A debtor to mercy alone

From Oremus Hymnal

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 Yes and Amen
and never was forfeited yet.
Things future, nor things that are now,
nor all things below and 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.
