Today is the feast day of John Donne - certainly the greatest of the metaphysical poets. A reluctant priest, he was nevertheless powerfully eloquent in devotional expression and passionate, I suppose, in all the ways a human being can be passionate.
These have long been my favorite of his lines and I have prayed them, actually, for many, many years now:
Batter my heart, three-personed God, for you
As yet but knock; breathe, shine, and seek to mend;
That I may rise, and stand, o'erthrow me, and bend
Your force to break, blow, burn, and make me new.
They are from his Holy Sonnet number fourteen.
