Book III, 66: On Christ, and our selves

I Wish a greater knowledge, then t'attaine
The knowledge of my selfe; A greater Gaine
Then to augment my selfe; A greater Treasure
Then to enjoy my selfe; A greater Pleasure
Then to content my selfe: How slight, and vaine
Is all selfe-Knowledge, Pleasure, Treasure, Gaine;
Vnlesse my better knowledge could retrive
My Christ; unlesse my better Gaine could thrive
In Christ; unlesse my better Wealth grow rich
In Christ; unlesse my better Pleasure pitch
On Christ; Or else my Knowledge will proclaime
To my owne heart how ignorant I am:
Or else my Gaine, so ill improv'd, will shame;
My Trade, and shew how much declin'd I am:
Or else my Treasure will but blurre my name
With Bankrupt, and divulge how poore I am;
Or else my Pleasures, that so much inflame
My thoughts, will blabb how full of fores I am:
Lord, keepe me from my selfe; 'Tis best for me,
Never to owne my selfe, if not in Thee.
