If Love dwelt not in Trouble, it could have nothing to love. But its
substance which it loves, namely the poor soul, being in trouble and
pain, it hath thence cause to love this its own substance and to deliver
it from pain, that so itself may by it be again beloved. Neither could
any one know what Love is, if there were no Hatred; or what friendship
is, if there were no foe to contend with. Or, in one word, if Love had
not something which it might love, and manifest the virtue and power of
love in working out deliverance to the Beloved from all pain and
trouble.
