Only a Prayer Meeting
Spurgeon once wrote in " The Sword and the Trowel" :

" A Wesleyan minister lately said that he was never more surprised in
his life than when he dropped into the Tabernacle, and found the
ground-floor and part of the gallery filled at a Prayer-meeting. He
believed that such a thing was almost without a parallel in London,
and that it accounted for the success of the ministry. We concur in his
impartial judgment. Will not all the churches try the power of prayer?"

A congregation without a prayer meeting is essentially defective in its organization,
and so must be limited in its efficiency.
