Llanwer ni ag ysbryd gweddi

Llanwer ni ag ysbryd gweddi -
  Ysbryd llawn o daerni dwys;
Ysbryd gofyn hyd nes derbyn,
  Y bendithion mwya'u pwys:
Ysbryd llawn o deimlad bywiog,
  Lanwo galon pawb o'r byw;
Boed yn amlwg ar eneidiau,
  Weithrediadau Ysbryd Duw.

May we be filled with a spirit of prayer -
  A spirit full of earnest tenacity;
A spirit of asking until receiving,
  The blessings of greatest weight:
May a spirit full of lively feeling,
  Fill the heart of all of the living;
Evident upon souls may the activities
  Of the Spirit of God be.
