Concwerwr yw

Concwerwr yw,
    fy Iesu a'm Duw, bob awr,
Clod iddo ef,
    trwy'r nef a'r ddaear lawr:
  Addawodd fod,
      trwy ddwfr a thân o'm plaid,
  A'i ddeheu law,
      gyflawnai fy holl raid.

Ai seren yw,
    a'i nerth yn chwalu'n llwyr,
Y tywyll nos,
    a holl gysgodau'r hwyr?
  'Rwy'n gwel'd o bell,
      ei llewyrch llon trwy ffydd,
  A 'nabod 'rwyf,
      mai hon yw'r seren ddydd;

Ai haul yw ef?
    rhoi llewyrch gras ar led,
Ei gylch a'i wres,
    trwy'r anial dir a red:
  Cenedloedd pell,
      wynebant at y ne',
  Gan lawenhau,
      pan ymddangoso efe.

gwelir: Ai seren yw?

A conqueror he is,
  my Jesus and my God, every hour,
Praise unto him,
    throughout heaven and the earth below:
  He promised to be,
      through water and fire on my side,
  With his right hand,
      he fulfilled all my need.

Is he a star,
    with his strength destroying completely,
The dark night,
    and all the shadows of the evening?
  I am seeing from afar,
      his cheerful radiance through faith
  And I know,
      that this is the daystar;

It he a sun?
    shedding the radiance of grace widely,
His circuit and his warmth,
    that runs through the desert land:
  Distant nations,
      they face heaven,
  Rejoicing,
      when he appears.
