O blentyn y nefoedd paham mae dy fron?

O blentyn y nefoedd!
  Paham mae dy fron
Mor ofnus wrth weled
  gwyllt ymchwydd y donn?
Mae'r dyfnder du tywyll
  yn rhuo, gwir yw;
Ond diogel yw'th fywyd -
  Mae'th Dad wrth y Llyw.

Daw'n fuan orfoledd
  diddiwedd i'th ran;
Draw'n disgwyl mae'th geraint
  oddeutu y lan:
Y disglaer lys acw,
  dy hoff gartref yw;
Mae Canan yn ymyl,
  a'th Dad wrth y Llyw.

Cŵyd bellach dy hwyliau,
  mae'r awel o'th du,
'Rwyt bron mynd i fynwes
  dy fwyn Brynwr cu;
Mae'th angor yn ddiogel,
  a'th Gadben yn fyw,
Mae'th gwch yn y porthladd,
  a'th Dad wrth y Llyw.

O child of the heavens!
  Why is thy breast
So fearful on seeing
  the wild surge of the wave?
The dark, black deep
  Is roaring, it is true;
But safe is thy life -
  Thy Father is at the Helm.

Soon will come endless
  joy to thy lot;
Yonder waiting are thy kin
  along the shore:
The shining court yonder,
  is thy beloved home;
Canaan is alongside,
  and thy Father at the Helm.

Raise thy sails now!
  The breeze is on thy side,
Thou art quite going to the breast
  of thy gentle, dear Redeemer;
Thy anchor is safe,
  and thy Captain is alive,
Thy boat is in the harbour,
  and thy Father is at the Helm.

O why, child of heaven,
  is thy faithless breast,
In viewing the tempest
  with terror oppressed?
The dark depths are roaring,
  but yield not to fear,
Thy vessel is safe,
  for thy Father doth steer.

Soon, soon endless joy
  shall encompass thy brow,
Thy friends on the shore
  are awaiting thee now:
Unfurl every sail,
  see the bright morn appear,
And Canaan is nigh,
  and thy Father doth steer.

Unfurl every sail,
  for the favouring breeze
Is urging thee on
  to the haven of peace:
Thine anchor is safe -
  thou to Jesus art dear:
Thou hast entered the port -
  and thy Father doth steer.
