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.
