Mae arnaf eisiau sêl

Mae arnaf eisiau sêl,
  A chariad at dy waith;
Nid rhag ofn y gosp a ddêl,
  Nac am y wobr chwaith;
Ond gwir ddymuniad llawn,
  Ddyrchafu'th gyfiawn glod,
Am i ti wrthyf drugarhau
  A chofio am dana'i 'rioed.

Rho grefydd gywir im',
  A ddalio rym y tân;
Yn ŵyneb rhyfel poeth a llym,
  O! Iesu, tyn fi 'mlaen;
Yn Salem yn y man,
  Heb ofnau dan fy mron,
Y seiniaf glod, heb boen na phla,
  Ymhlith y dyrfa lon.

I want a zeal,
  And love for thy work;
Nor from fear of the punishment to come,
  Nor for the prize either;
But a full, true desire,
  To raise thy righteous praise,
For thy mercies to me
  And remembering me always.

Give true faith to me,
  That it keep the force of the fire;
In the face of hot and sharp war,
  O Jesus, draw me forward;
In Salem soon,
  Without fear under my breast,
I will sound praise, without pain or plague,
  Amongst the cheerful throng.

I want a true regard,
  A single, steady aim,
Unmoved by threat'ning or reward
  To Thee and Thy great Name.
A jealous, just concern
  For Thine immortal praise;
A pure desire that all may learn
  And glorify Thy grace.

I rest upon Thy Word;
  The promise is for me;
My comfort and salvation, Lord,
  Shall surely come from Thee.
But let me still abide,
  Nor from my hope remove,
Till Thou my patient spirit guide
  Into Thy perfect love.
