Assurance

S Teresa of Ávila, by Peter Paul Rubens

  Let nothing disturb thee,
Nothing affright thee;
All things are passing;
God never changeth; 
Patient endurance 
Attaineth to all things; 
Who God possesseth 
In nothing is wanting;
Alone God sufficeth.


- Saint Teresa of Ávila, in Longfellow's classic translation from the Spanish.
