O am gael calon lân difrad

O am gael calon lân, difrad,
  Fy Nuw, i'th foli di;
Beunydd yn teimlo rhîn dy gwaed,
  Dywalltwyd drosof fi.

Yn galon dyner, hawddgar, fwyn,
  Gorsedd fy Mhrynwr Glân;
Lle y teyrnasa Iesu Grist,
  O hyd yn ddiwahân.

Calon ddrylliog, isel wâr,
  Grediniol, gywir, lân!
Yn glynu wrth fy nefol gâr,
  Er gwaethaf dw'r a thân.

Wedi ei hadnewyddu yn llwyr, -
  Yn llawn o gariad Duw;
Un berffaith, uniawn, bur, a da,
  Fel calon f'Arglwydd gwiw.

Yr un yw'th galon di bob awr,
  Hi dawdd wrth ddynol wae;
Dy gariad a'th dosturi mawr,
  O gad i mi fwynhau.

Nis gall fy nghalon orphwys byth,
  Nesitit greu fy hedd;
Nes adfwynhau fy Eden bêr,
  A'm hadfer ar dy wedd.

Ffrwyth dy wefusau grasol moes
  I mi, yn heddwch mawr;
Y mann cudd, y bywiol bren,
  A'r gareg wèn ei gwawr.

Dy anian rasol, Arglwydd Dduw,
  Ar fyrder moes i mi,
'Sgrifena'th enw, - Cariad yw!
  O fewn fy nghalon i.

O to have a clean, sincere heart,
  My God, to praise thee;
Daily to feel the merit of thy blood,
  Shed for me.

A tender, pleasant, gentle heart,
  The throne of my holy Redeemer;
Where Jesus Christ reigns,
  Always inseparably.

A broken, lowly, obedient heart,
  Believing, true, clean!
Sticking to my heavenly kinsman,
  Despite water and fire.

Having been renewed completely, -
  Full of the love of God;
A perfect, upright, pure and good one,
  Like the heart of my worthy Lord.

Thine heart is the same every hour,
  It springs from human woe;
Thy love and thy great mercy,
  O let me enjoy.

My heart can never rest,
  Until thou create my peace;
Until reviving my sweet Eden,
  And recreate me as thy countenance.

The fruit of thy gracious lips give
  To me, in great peace;
The hidden manna, the lively tree,
  And the stone with a bright dawn.

Thy gracious nature, Lord God,
  Quickly give to me,
Write thy name, - it is Love!
  Within my heart.

O for a heart to praise my God,
  A heart from sin set free,
A heart that always feels Thy blood
  So freely shed for me.

A heart resigned, submissive, meek,
  My great Redeemer's throne,
Where only Christ is heard to speak,
  Where Jesus reigns alone.

A humble, lowly, contrite, heart,
  Believing, true and clean,
Which neither life nor death can part
  From Christ who dwells within.

A heart in every thought renewed
  And full of love divine,
Perfect and right and pure and good,
  A copy, Lord, of Thine.

Thy tender heart is still the same,
  And melts at human woe:
Jesus, for thee distressed I am,
  I want Thy love to know.

My heart, Thou know'st, can never rest
  Till Thou create my peace;
Till of mine Eden repossessed,
  From self, and sin, I cease.

Fruit of Thy gracious lips, on me
  Bestow that peace unknown,
The hidden manna, and the tree
  Of life, and the white stone.

Thy nature, gracious Lord, impart;
  Come quickly from above;
Write Thy new name upon my heart,
  Thy new, best name of Love.
