[Mae'r goleuni / Y golau / Y goleuni] sy'n ninas ein Duw

Y goleuni sy'n ninas ein Duw,
  Sy tu hwnt i amgyffred un dyn,
'Does neb all ei weled, a byw,
  Ond y dorf ogoneddus ei hun:
'Dyw grisial yn ngolwg yr haul,
  Neu wydr f'ai lawer mwy pur,
I lewyrch y nefoedd ddim ail:
  Fy Iesu yw'r ffynnon yn wir.

Mae yno dri Pherson yn bod,
  Ac etto mewn sylwedd ond Un,
Gogyfuwch mewn gallu a chlod,
  I wared plant Adda'n gyttûn;
Yn hyn rhyw ddyfnderoedd y sy
  Rhy fawrion i'w chwilio hwy 'mlaen,
Yn drech na hwynt-hwythau sy fry
  I'w gwybod hwy allan yn lân.

'Does mesur amseroedd byth fry,
  Dim oriau cyffelyb i'r byd;
Myn'd heibio ryw oesoedd y sy
  Wrth ganu i'r Drindod ynghyd;
'R holl nefoedd, wrth weled ei ras,
  Sy'n synu, yn canu'n fwy hy'
Ganiadau newyddion eu blas:
  Wel, dyna'r digrifwch sydd fry.

  Mae hwnt i amgyffred un dyn;
'Does neb all ei weled a byw,
  Ond y dorf ogoneddus ei hun:
'Dyw grisial yngolwg yr haul,
  Neu wydyr f'ai lawer mwy pur,
I lewyrch y nefoedd ddim ail -
  Fy Iesu yw'r ffynnon yn wir.

Tuag ato mae wyneb ei saint
  Oddiamgylch, yn rhes ar ol rhes;
Yn dyrfa aneirif o faint,
  Rhai 'mhellach oddiwrtho, rhai'n 'nes:
Dysgleirdeb ei wyneb â 'mhell,
  Mil pellach na'r
      haul yn ei rod;
Ei fwynhau ef mae'r pellaf yn well
  Nag allwyd amgyffred erioed.

'Does angel, na seraph, na sant,
  Byth yno'n dysgleirio 'hono'i hun;
Pe ciliai f'Anwylyd i bant,
  Fe d'wyllai,
      fe dduai pob un:
Fe yw Afon y Bywyd sy' fry,
  Fe yw'r Manna cuddiedig a drud,
Efe yw hyfrydwch y llu;
  Ië, 'm Iesu yw'r nefoedd i gyd.

The light that is in the city of our God,
  Which is beyond the grasp of any man,
No-one can see it, and live,
  But the glorious host themselves:
Neither the crystal in sight of the sun,
  Nor glass would be much more pure,
Compared with the radiance of heaven:
  My Jesus is truly the source.

There are there three Persons being,
  And yet in substance but One,
Equally high in power and esteem,
  To deliver Adam's children in agreement;
In this there are some depths
  Some great things to seek out,
It is beyond those that are above
  To know them altogether completely.

There is never any measure to times above,
  No hours similar to the world;
Some ages pass
  While singing to the Trinity together;
The whole heavens, on seeing his grace,
  Are astonished, singing more boldly
Songs with a new flavour:
  See, that is the pleasure that is above.

The light thatis in the city of our God,
  It is beyond the grasp of any man;
There is no-one that can see him and live,
  But the glorious throng itself:
Not the crystal in the view of the sun,
  Or glass that was many time more pure,
Is like to the radiance of heaven -
  My Jesus is the Fount truly.

Towards him is the face of his saints
  From around him, in row upon row;
As a throng innumerable in extent,
  Those further away from him,
      those nearer:
Radiant his face and far,
  A thousand times further that the
      sun in its orbit;
Enjoying him is the furthest better
  Than ever could be comprehended.

There is no angel, or seraph, or saint,
  Ever there shining from himself;
If my Beloved retreated away,
  It would become dark,
      it would become black for everyone:
  He is the hidden and costly Manna,
He is the delight of the host;
  Yes, my Jesus is all of heaven.
