"The only power to oppose evil is love - strong, enduring love -- a  benevolence which no crime or wretchedness can conquer, and which therefore can conquer all. Miserable indeed will your position be if this spirit does not possess you, if a deep sympathy with your suffering fellow-creatures does not compel you, as it were, to seek their homes and identify with them. 

Nothing but Christ's spirit, that which carried Him to His cross, can carry you through your work. Go then, with this love, and it will be mightier than the sword of the magistrate, or the armies of monarchs to conquer evil. This spirit will touch the heart which has hardened itself against all other influences. It will pierce the conscience which is impregnable against the most vehement rebuke. It will say to the reckless transgressor, in the only language he can understand, that he is not an outcast from his race; and it will reveal to the desponding sufferer a love higher than your own, and bring back his lost faith in God. William Ellery Channing.
