Hwylia 'nghalon, O! fy Arglwydd,
  I glodfori rhyfedd ras;
Galw mae dy drugareddau
  Am y gān bereiddia'i blas;
Dysg im ryw nefolaidd fesur
  Genir gan y dyrfa fry;
Boed dy gariad digyfnewid
  Byth yn destun mawl i mi.

Codaf yma f'Ebeneser -
  Gras a'm nerthodd hyd yn hyn;
Yn dy ras gobeithiaf eto
  Am fy nwyn i Seion fryn,
Iesu ddaeth o'r nef i'm ceisio,
  A mi'n crwydro 'mhell o dre;
Ac i'm gwared o'm peryglon
  Rhoes ei fywyd yn fy lle.

Hwylia'm calon, O, fy Arglwydd,
  I glodfori'th rhyfedd ras,
Galw mae dy drugareddau
  Am y gān bereiddia'i blās;
Dysg im' ryw nefolaidd fesur
  Genir gan y dyrfa fry,
Boed dy gariad digyfnewid
  Byth yn destun mawl i mi.

Ni all calon dyn ddychmygu,
  Ni all tafod draethu i ma's
Pa mor ddirfawr yw fy nyled,
  Anwyl Arglwydd, i dy ras:
Cymer feddiant llawn ohonof,
  Cadw'm calon yn ei lle;
Gwaith fy mywyd bellach fyddo
  Datgan clodydd gras y ne'.

gwelir: Ni all calon dyn ddych'mygu

Tune my heart, O my Lord!
  To extol wonderful grace;
Calling are thy mercies
  For the song of sweetest taste;
Teach me some heavenly measure
  To be sung by the throng above;
Let thy unchangeable love be
  Forever a theme of praise for me.

I will raise here my Ebenezer -
  Grace has strengthened me thus far;
In thy grace I hope still
  To be led to Zion hill,
Jesus who came from heaven to seek me,
  And I wandering far from home;
And to deliver me from danger
  He gave his life in my place.

Tune my heart, O my Lord,
  To extol thy wonderful grace;
Calling are thy mercies
  For the song of sweetest taste,
Teach me some heavenly measure
  Sung by the throng above,
Let thy unchangeable love be
  Forever a theme of praise for me.

The heart of man cannot imagine,
  No tongue can set forth
How enormous is my debt,
  Dear Lord, to thy grace:
Take full possession of me,
  Keep my heart in its place;
May the work of my life henceforth be
  To declare the praises of heaven's grace.

1. Come, thou fount of every blessing,
  Tune my heart to sing Thy grace;
Streams of mercy never ceasing,
  Call for songs of loudest praise;
Teach me some melodious sonnet,
  Sung by flaming tongues above;
Praise the mount - oh, fix me on it,
  Mount of God's unchanging love.

2. Here I raise my Ebenezer,
  Hither by Thy help I come;
And I hope, by Thy good pleasure,
  Safely to arrive at home:
Jesus sought me when a stranger,
  Wand'ring from the fold of God;
He, to save my soul from danger,
  Interposed his precious blood.

1. Come, thou fount of every blessing,
  Tune my heart to sing Thy grace;
Streams of mercy never ceasing,
  Call for songs of loudest praise;
Teach me some melodious measure,
  Sung by flaming tongues above;
O the vast, the boundless treasure,
  Of my Lord's unchanging love.

3. O to grace how great a debtor
  Daily I'm constrained to be!
Let Thy goodness, like a fetter,
  Bind my wandering heart to Thee.
Prone to wander, Lord, I feel it,
  Prone to leave the God I love;
Here's my heart, O take and seal it,
  Seal it for Thy courts above.
