Tune is basically that of "Red is the Rose"/"Loch Lomond". This tune has a range of styles in which it can be sung but this video is pretty much the style I use. https://www.youtube.com/watch?v=NBS5rqLY68U
When sin had spread to the ends of the earth,
And God almighty descended,
He did not destroy as He justly may have done,
He died for sinners salvation.
Lord Jesus Christ have mercy upon me,
When all my other hope flees,
To you my hope, this ever my plea,
Lord Jesus have mercy upon me.
And when through life's trials and temptations I walk,
And sin's deadly flower smells so sweet,
Help me remember I died to death and sin,
And in our cross find relief.
And when at the end of this life I arive,
Should I think o'er all of my days,
Rememb'ring how often I failed thee oh God,
May I not forget thy grace.
Vain all the things that this world doth desire,
And vain all that lies in me,
But true is my shepherd, the Lamb that was slain,
For all of my sins upon Calv'ry.
Tune derived from "The Nightingale" which can be heard here: https://www.youtube.com/watch?v=65_jHeXZy3I
When man in the garden his nakedness saw,
And perceived his transgression of thy holy law,
He confessed his sin to thee that he rightly was damned,
And you promised him a savior, clothing him in the Lamb.
To you my precious Jesus, my savior I sing,
Though I am unworthy of any good thing,
You who dwell in the glory of heaven so fair,
Also journeyed to Calvary to die for me there.
When Cain slew his brother and shed his kin's blood,
From the ground it cried out condemning him to God,
To your Supper you call me saying what you have said,
Take and drink this is my blood to forgive it was shed.
When wickedness spread out upon the earth's face,
You determined to put an end to Adam's lost race,
In your baptism of the world you killed sinful man,
And the sinner saved by grace emerged according to your plan.
Here I stand and remember the stories of old,
And I see just how quickly that my faith turns so cold,
Yet you strengthen, preserve me in the faith that is true,
Until that glorious last day when all things are made new.
