Protestant
John Owen’s short classic on putting sin to death—often called The Mortification of Sin. Restored so his method stays visible on the page — an edition meant for deep reading, not a quick PDF skim.
Kindle edition — on Amazon
Kindle edition sold by Amazon. This edition is for readers who want the work itself, not a summary.
Text from William H. Goold’s Works of John Owen, Volume VI (1862) — the treatise alone, following the corrected 1658 edition.
Prepared for deep reading: we restore Owen’s argument as nested structure, so the steps of the method stay visible on the page. Spelling and punctuation are lightly modernized; his theological vocabulary and archaic second person remain.
Elsewhere, free PDFs give you the words. This edition is designed so you can stay with the argument — and you keep the book.
Three companion volumes on the same question: How does the believer put sin to death?
