My worthiness is all my doubt

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.
