O Arglwydd rho dy allu mawr

O Arglwydd! rho dy allu mawr
  I'm nerthu fyn'd yn mlaen;
Dy iachawdwriaeth yw fy ngrym,
  Fy nghoncwest a fy nghân.

Rho nerth i rodio er dy glod,
  Ac iti bellach fyw;
A threulio mywyd gyda blas,
  I ganmol gras fy Nuw.

O! cau fy llygaid rhag im' wel'd
  Pleserau gwag y byd;
Na'd imi wyro byh oddiar
  Dy lwybrau gwerthfawr, drud.

gwelir:
  Iesu difyrrwch f'enaid drud
  'Rwy'n morio tua chartre'm Nêr

O Lord, give thy great power
  To strengthen me to go forward;
Thy salvation is my force,
  My conquest and my song.

Give strength to walk for thy acclaim,
  And for thee henceforth to live;
And spend my life with a taste,
  To praise the grace of my God.

Oh, close my eyes lest I see
  The empty pleasures of the world;
Do not let me wander ever away from
  Thy valuable, precious paths.
