Pastor Jeff Walper

Bible 3/4

Jeff Walper is the Junior/Senior Bible teacher at Weimar Academy. He is married to Jodi Davis; they are blessed with 3 daughters: Olivia, Rubi, and Elin. Their family moved to Weimar in 2019. Before giving his life to Jesus Christ in 1998, Jeff desperately searched for meaning in life. He had been raised in a nominal Adventist home. He knew about Jesus, but hadn’t received the gospel of Jesus Christ. Dropping out of college at the age of 19, Jeff, along with a friend, traveled from Atlanta, Georgia to Kodiak, Alaska in search for something more. Jeff spent portions of the next 4 years living in a tent, staying at a homeless shelter, working on fishing boats, working in a logging camp, working at a ski resort, washing dishes, and then working as a bartender. In 1998, while bartending, Jeff received a piece of gospel literature that led him to receive the gospel of Jesus Christ and thus give his life to his Saviour. Immediately Jeff quit his bartending job and trained to be a missionary for Jesus Christ. After a month of intensive training and two months of waiting for his visa, the Lord sent him to Hatsukaichi, Japan as a Gospel missionary. Jeff has been serving Jesus Christ as a missionary for the past 21 years. He has served the Lord as a Hospital Chaplain, a Church Pastor, a Church Planter, a Colporteur, a Medical Missionary, and now as the Chaplain of Weimar’s NEWSTART Program and Bible Teacher at Weimar Academy. Jeff has a burden for souls. His vision for ministry includes helping others to find their value in Jesus Christ and thus discover their identity and mission in life.
