Jail THEOLOGY (Jeff Grupp OFFICIAL)

My name is Jeff Grupp. I am a jail preacher in Michigan. I am a former atheist, but I was converted to Christianity after a series of supernatural experiences during my 20s and 30s. My theology website is jailtheology.net. I am the founder and Lead Chaplain of Kalamazoo Jail Ministry (kalamazoojailministry.org), in Kalamazoo, MI. I am a former college lecturer of philosophy and logic. I am the author of Hyper-Calvinist Universal Salvation (Wipf and Stock 2024), which I deem is a new systematic theology, that shows Scripture to be perfect logic, especially by revealing novel theological and scriptural breakdown to some of the largest gaps in Biblical and systematic theology (why is there evil, what is the Lake of Fire, how can GOD be sovereign and not create sin, what does “every knee shall bow” mean, and so on). I am the author of 17 professional articles in philosophy and theology. And I am a PhD student at California Institute of Integral Studies, where I'm studying medieval theology
