J.J. Weller is a missionary and author from St. Petersburg, Florida. Since 2014, he has traveled the world through Message Ministries to win the lost, call prodigals home, and train saints in biblical evangelism. During that time, he’s had the privilege to preach salvation to thousands—including many in unreached people groups—and to activate hundreds of believers in biblical evangelism. He studied shortly at Fire School of Ministry in Charlotte, North Carolina, then received his B.A. in Professional and Strategic Writing from Regent University. He has co-written a missions training book, Invasion of Light: How Jesus Can Use You and Me to Win the Battle for Souls and Societies, written an outreach book, The Cure for Death: Finding Eternal Life in the Age of COVID-19, created evangelistic and discipleship materials in multiple languages, and recorded one album of Christian music. He lives with his wife, Cynthia, and children, Autumn Hope and William, in St. Petersburg, Florida.
