True Christianity: A Treatise on Sincere Repentance, True Faith, The Holy Walk of the True Christian, Etc. by John Arndt

“If ever any man was competent to write on true Christianity, that man was John Arndt. It had become his very life; it entered into the very center of his own experience; it was an essential part of his being, and hence it was only necessary to let the mouth utter that, of which the heart was full. We need not be surprised that this book, at its first appearance, met with undivided approbation and an extensive sale.
