Charles Walker (1791-1870) was a brilliant and gifted man who was burdened to see the young taught the truth of God in their own language. In his own words: "The writer of the following little work has attempted to discuss important doctrines of the Gospel, and to urge its correspondent duty on the conscience of the reader. And he has attempted to do this in the language which children may understand, and in a form which may excite their attention." This volume was originally published as two separate volumes on the gospel duties of Repentance and Faith. Examples are drawn from both Bible and Church history to demonstrate the difference between true and false faith, and true and false repentance. This was originally published by The American Tract Society and went through many editions.
