an harvest to faithful labour?  The same exertion, that would instruct hundreds in the country, may reach thousands in the city.  Public sentiment has too long checked the movements of sympathy for these congregated thousands.  A voice, almost unbroken, has sounded out; ’Peculiar and insuperable difficulties prevent a general revival in cities:  such are the occupations, such the habits, such the temptations, and such the superabounding iniquity, that it were visionary to hope for any general and powerful work of mercy.’  Well, then, had we not better give all up; and let human nature here sink into its natural channels; and let multitudes before our eyes continue to crowd the gates of the second death!  O God, forbid such cowardice, cruelty, and treachery in thy servants!  No; we will not thus surrender immortals.  While there is grace or even nature in our hearts, we will not.  We have, indeed, heard of difficulties, till the heart is pained, and the soul is wearied.  But where are these insuperable difficulties to be found?  Not in the Scriptures of God, surely; not in the result of apostolic labours; but in the unbelief and inaction of modern Christians.  “God is no more hostile to cities than to villages:  his Spirit is as free, and his offers of salvation as full, to the people of the crowded city, as of the open country.”  Let the advantages then be embraced.  Let the power be concentrated.  Let the sacramental host arise; and the work is done.  And instead of being overwhelmed with shame and deserved reproach, we may joyfully say to such as pass by; “Walk about Zion, and go round about her:  tell the towers thereof; mark ye well her bulwarks, consider her palaces; that ye may tell it to the generation following.  For this God is our God for ever and ever.”  “Then the sons also of them that afflicted Zion shall come bending unto her; and all they that despised her shall bow themselves down at the soles of her feet; and they shall call her the City of the Lord—­the Zion of the Holy One of Israel.”

VI. A sixth reason for special efforts in behalf of Cities is, the influence which they exert on the country and on the world.

Look to any nation, whether ancient or modern; throw the map before you; fix your eye upon the spots that bear rule; that command the attention of the enterprising, and busy the thoughts of statesmen.  You have fixed it upon the cities of the world.  Where was the strength of Italy, if not in Rome, once mistress of the world?  Where the strength of Greece, if not in Athens, the mother of arts and refinement?  And where is the strength of our Republic, if not in our cities and large towns?  There talent in every art and profession is fostered, and exerts peculiar influence.  There wealth concentrates its millions upon millions, to exert extensively a blasting or brightening influence on society.  There the press daily sends out its thousands and its tens of thousands
