Part Three: Love

XXXVI

MY worthiness is all my doubt,
  His merit all my fear,
Contrasting which, my qualities
  Do lowlier appear;
  
Lest I should insufficient prove         
  For his beloved need,
The chiefest apprehension
  Within my loving creed.
  
So I, the undivine abode
  Of his elect content,       
Conform my soul as ’t were a church
  Unto her sacrament.
