O Iesu galw fi

O! Iesu, galw fi
  Â'th addfwyn, dyner lef,
O ganol anial mawr y byd
  I lwybrau clyd y nef.

O! Iesu, arwain fi
  Â'th gref, garedig law,
Ar hyd y ffordd a drefnaist Ti
  I fro'r goleuni draw.

O! Iesu, nertha fi
  O hyd â'th Ysbryd Glân, 
I goncro anawsterau'r daith,
  A throi fy ngwaith yn gân.

O Jesus call me
  With thy gentle, tender call,
From the middle of the great desert of the world
  To the cosy paths of heaven!

O Jesus, lead me
  With thy strong, loving hand,
Along the way which Thou preparedst
  To the vale of yonder light!

O Jesus, strengthen me
  Always with thy Holy Spirit,
To conquer the difficulties of the journey,
  And turn my work into song.
