Keith Keyser was born and raised in southeastern Pennsylvania, USA. He was brought up in a Christian home and converted at the age of seven through a knowledge of his sinfulness and Christ’s sufficiency to save. His gift of teaching was discovered and developed in the local assembly in Gilbertsville, PA, where he continues to fellowship (Grace Gospel Chapel). After working in the car rental industry, Keith left secular employment to give all of his time to the Lord’s service in 1999. He is mainly engaged in itinerant Bible teaching and gospel preaching throughout North America, Western Europe, and Asia. He also writes various articles on the Scriptures for Christian publications and websites.
