Sustainable revival?

The New York revival of 1858 was based upon a lunchtime prayer meeting, at first attended by just 6 people. Within weeks hundreds upon hundreds were flocking to such prayer meetings each day. Samuel Prime quotes from the religious press of the day:

'The church, or more truly, individual churches, have often made what might be called exhaustive efforts for the conversion of sinners. They have taxed to the utmost for a few weeks both soul and body of every earnest man they could enlist. Such efforts must be relaxed. Flesh and blood cannot sustain them. But the present revival has had no such history. The church is still fresh, and may labor on indefinitely just as she has been laboring, and that without sinning against any law of mental or physical health. This revival has not overtaxed us; it has only toned us up. It has brought religion into alliance with our ordinary engagements; it has given to our social character a completeness and balance which it never had before. So far as it has gone it is an advance toward soundness and strength, and to fall back from it is not to rest after labor, but to be palsied.'
