Arglwydd grasol nertha'm ffydd

Arglwydd grasol, nertha'm ffydd,
Pan dywyllo ganol dydd;
Ofn y cwmwl arnom sydd:
  Llewyrcha arnom ni.

Os cawn olwg ar dy wedd,
Daw i'n mynwes ffrwd o hedd;
Ac nid ornwn fyd na bedd:
  Llewyrcha arnom ni.

Cilied egwch lliw a llun,
A phob pleser yn gytūn
Ddwg o'n bryd Dydi dy Hun:
  Llewyrcha arnom ni.

Pan fo'r niwl ar obaith oes,
Ninnau'n plygu dan y groes,
Gweld dy wedd iachā bob loes:
  Llewyrcha arnom ni.

Os doi Di i'r nos, ni rydd
Cwmwl gwmwl ar ein ffydd;
Cwmwl gweddniwidiad fydd:
  Llewyrcha arnom ni.

O dan las neu dywyll nen,
Arain ni i'th wynfa wen;
Nes in ddod i'r byd di-len,
  Llewyrcha arnom ni.

Gracious Lord, strengthen our faith,
When mid-day darkens;
We fear the cloud:
  Shine thou upon us.

If we get a sight of thy countenance,
A stream of peace comes to our breast;
And we fear neither world nor grave:
  Shine thou upon us.

Should the fairness of colour and image,
And every pleasure in agreement
Take from our mind Thee thyself:
  Shine thou upon us.

Where there be cloud on the hope of an age,
And we be bowing under the cross,
Seeing thy countenance shall heal every pang:
  Shine thou upon us.

If Thou come to the night, it will not bestow
A cloud of cloud upon our faith;
A cloud of transfiguration it shall be:
  Shine thou upon us.

Under a blue or a dark sky,
Lead us to thy bright, blessed place;
Until we come to the unveiled world,
  Shine thou upon us.
