John Donne — Oh to vex me contraryes meet in one Holy Sonnet XIX

Oh, to vex me, contraryes meet in one: Inconstancy unnaturally hath begott A constant habit; that when I would not I change in vowes, and in devotione. As humorous is my contritione As my prophane Love, and as soone forgott: As ridlingly distemper'd, cold and hott, As praying, as mute; as infinite, as none. I durst not view heaven yesterday; and to day In prayers, and flattering speaches I court God: To morrow I quake with true feare of his rod. So my devout fitts come and go away Like a fantistique Ague: save that here Those are my best dayes, when I shake with feare.
