I have a old book given to me many years ago by my dearly loved aunt. It is 'Great Souls at Prayer'.
This prayer was written by Jeremy Taylor who lived in the time of Oliver Cromwell, 1613-1667.
Guide me, O Lord, in all the changes and varieties of the world; that in all things that shall happen, I may have an evenness and tranquillity of spirit; that my soul may be wholly resigned to Thy divinest will and pleasure, never murmuring at Thy gentle chastisements and fatherly correction.
Amen
