Studying the Bible verse by verse can feel overwhelming without a guide — especially when you want to go deeper than a surface-level reading but don't have a seminary library at your disposal. Enduring Word is that guide: a free, comprehensive Bible commentary covering every book from Genesis to Revelation, written by Pastor David Guzik in a warm, accessible style that serves pastors preparing sermons and new believers reading Scripture for the first time alike.^1
What makes Enduring Word distinctive is how it blends scholarly depth with pastoral warmth. The commentary weaves in insights from historical theologians like Spurgeon, Poole, Trapp, and Clarke alongside Guzik's own verse-by-verse teaching notes, giving readers a sense of how the Church has understood these passages across centuries. With more than 11,000 pages of commentary, hundreds of audio and video teachings, and content available in over 15 languages, Enduring Word has grown from one pastor's personal notes into one of the most widely-used Bible study resources on the internet — surpassing 6 million page views per month.^2
David Guzik never set out to write a commentary. In 1996, as a young Calvary Chapel pastor, he submitted his digital teaching notes to the fledgling Blue Letter Bible website alongside an estimated 300 other pastors. He turned out to be the only one who followed through. Those notes — originally prepared on a Kaypro II computer in the late 1980s — became the foundation for what is now used by millions worldwide.^4 Guzik has served in ministry for over 40 years, including church plants in California and more than seven years as a missionary and Bible college director in Germany.^5
Why Christians Love Enduring Word: "When I read David's commentaries, I often feel like I've had a good meal. I feel satisfied, content and ready to face the day. David's notes are rich in research, soaked in prayer and dedication and anointed by the Lord."^6 Users across the world describe how the commentary has transformed their daily study — one cowboy church pastor in Texas wrote, "I read and understand your efforts to expand the holy Word... I will pray for God to continue to use you mightily in His service."^6 An App Store reviewer shared, "I'm so thankful Pastor David Guzik's Bible commentary is now available as an app."^7 Another on Google Play wrote, "I had been using the web version of the commentary for a few years, but it is much easier to quickly go to a chapter on the app."^8
In November 2025, Thomas Nelson published the Enduring Word Study Bible (NKJV), bringing Guzik's pastoral commentary into a physical study Bible format with notes for every chapter of Scripture and over 200 word studies.^9
