Keith Keyser (birth year unavailable–) is an American preacher and Bible teacher whose itinerant ministry has focused on spreading biblical teaching and the gospel across North America, Western Europe, and Asia for over two decades. Born and raised in southeastern Pennsylvania, he grew up in a Christian home and was converted at age 7, coming to a personal understanding of his sinfulness and Christ’s sufficiency to save. His gift for teaching emerged within the local assembly at Grace Gospel Chapel in Gilbertsville, Pennsylvania, where he continues to fellowship. After working in the car rental industry, Keyser left secular employment in 1999 to dedicate himself fully to ministry. Married to Naomi since 2005, they have four children—Anastasia, Nadia, Fiona, and Micah—who often join him in his travels. Keyser’s preaching career centers on an itinerant schedule, delivering sermons and Bible studies at churches, conferences, and camps, emphasizing expository teaching rooted in Scripture. He has authored commentaries, such as The Epistle of Paul to the Philippians: An Exposition, and contributes articles to Christian publications, including Precious Seed’s “Day by Day” devotional series. His messages, available on platforms like SermonAudio and Voices for Christ, cover topics from gospel fundamentals to in-depth scriptural analysis, reflecting his commitment to equipping believers. Based in Gilbertsville, he also produces a podcast through his website, goodwordsandworks.com
