The Wordless Book is a Christian evangelistic book. Evidence points to it being invented by the famous London Baptist preacher Charles Haddon Spurgeon in a message given on January 11, 1866 to several hundred orphans regarding Psalm 51:7 “Wash me, and I shall be whiter than snow.” It is called a “book,” as it is usually represented with pages, although it can be shown on a single page or banner.

​

The book consists of several blocks of pure color that, in sequence, represent a nonverbal teaching tool about the way of salvation through Jesus for the instruction of children, the illiterate, or people of different cultures. However, the presentation of the book is meant to be a verbal experience, providing the child (or adult) a visual cue to learn the Gospel and entrust their life to Christ.
