Classic Poem

Toss not my soul, O Love, 'twixt hope and fear.
Show me some ground where I may firmly stand
Or surely fall; I care not which appear,
So one will close me in a certain band.

Take me, Assurance, to thy blissful hold,
Or thou, Despair, unto thy darkest cell.
Each hath full rest, the one in joys enrolled,
Th'other, in that he fears no more, is well.
