During these crusades, Moody pioneered many techniques of evangelism: a house - to - house canvass of residents prior to a crusade; an ecumenical approach enlisting cooperation from all local churches and
evangelical lay
leaders regardless of denominational affiliations; philanthropic support by the business community; the rental of a large, central building; the showcasing of a gospel soloist; and the use of an inquiry room for those
wanting to repent.
