John G. Reisinger (1924–2018) was an American preacher, evangelist, and author whose ministry significantly shaped the development of New Covenant Theology within evangelical Christianity. Born in Pennsylvania, he grew up in a context that led him to military service during World War II, where he served with the U.S. Navy Seabees in the Pacific Theater. Converted in his early twenties, Reisinger initially pastored in Pennsylvania and New York before founding Grace Community Church in Webster, New York, in 1966, where he served as minister for many years. Married to Rosemary for 70 years until her death in 2016, he raised two children—Jean and Robert—and became a grandfather to nine and great-grandfather to eight, grounding his ministry in a strong family life. Reisinger’s preaching career was marked by his role as a pioneer of New Covenant Theology, advocating a theological framework that emphasizes Christ as the final lawgiver, distinct from both Covenant Theology and Dispensationalism. He authored 28 books, including Tablets of Stone, Abraham’s Four Seeds, and In Defense of Jesus, the New Lawgiver, which clarified profound truths with simplicity, influencing countless believers and pastors. Based later in Canandaigua, New York, he preached across the U.S., often at conferences like the John Bunyan Conference, and his teachings—available through Cross to Crown Ministries and Monergism—focused on God’s sovereignty, grace, and the believer’s assurance. Reisinger died in 2018 at age 94, leaving a legacy as a humble, gracious teacher whose work continues to inspire a Christ-centered faith.
