Conversion is not the smooth, easy-going process some men seem to think... It is wounding work, this breaking of the hearts, but without wounding there is no saving... Where there is grafting there will always be a cutting, the graft must be let in with a wound; to stick it onto the outside or to tie it on with a string would be of no use. Heart must be set to heart and back to back or there will be no sap from root to branch. And this, I say, must be done by a wound, by a cut.
