I've posted this before, but it bears repeating. Again and again, actually. It is one of my favorite poems, a sonnet by John Donne (priest), whose liturgical feast is on my birthday.
Batter my heart, three-person'd 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.
I, like an usurpt town, to another due,
Labour to admit you, but Oh, to no end,
Reason your viceroy in me, me should defend,
But is captiv'd, and proves weak or untrue.
Yet dearly I love you, and would be loved fain,
But am betroth'd unto your enemy:
Divorce me, untie, or break that knot again,
Take me to you, imprison me, for I
Except you enthrall me, never shall be free,
Nor ever chaste, except you ravish me.
