He is passionate about defending and proclaiming the truth of the Gospel in winsome and bold ways. Miller lives with his wife Melinda and three children in Indiana. 


I was raised a sixth generation Mormon in Salt Lake City, Utah, with ancestors who were direct acquaintances with Joseph Smith and Brigham Young. Although Utah Mormonism is less insulated now, growing up I was honestly unaware that there were so many other options outside of Mormonism. But I was not concerned. I felt secure in my own religion.

I was invited to spend the summer of 1988 with a friend at his home in California. But his father made it contingent upon our attending a non-denominational Christian camp there called Hume Lake. Although I was not living the ideal Mormon life at the time (I was "living it up" a bit as an adolescent), I had no thought of ever changing religions. I still understood Mormonism to be the one true religion. I figured that our heavenly father was a loving heavenly father and would forgive my wrongdoing regardless of my adolescent behavior. After all, I surmised that I was not really that bad and I was bound to end up in one of the degrees of glory anyway. So there was no urgency for repentance just yet. If it were not for the appeal of spending the entire summer on California beaches, I probably would not have attended the camp at all.

I arrived at Hume Lake without any great expectations. If anything, like many high school guys, I suppose I was looking for cute girls. To my surprise, the camp speaker delivered a message that week on the topic of hell with a robust presentation of the Gospel. My soul resonated with the message and for the first time in my life I understood my need for forgiveness. Devastated and in tears, I realized I was a sinner and could not merit forgiveness. I was doomed without Christ! My fear of leaving what I thought was the truth in Mormonism was minimized, however, by the security I found in Christ and it being further authenticated by seeing Christ's love displayed through the people in a way I had not previously encountered. There was something authentic and non-religious about it. Even with my religious upbringing, I never experienced God's love in that way until I met these people and then met their source, Jesus Christ.

Later that summer, I asked and received approval from my mother to live in California for my junior year of high school. I was both baptized and discipled that seminal year. Returning to Utah for my senior year was a challenge. On the one hand, I quickly found fellowship with some young and passionate Christians. We were challenged by the call to evangelism in the New Testament. We spent many nights "street preaching" in Salt Lake City by the Mormon Temple and on the University of Utah campus. On the other hand, I recall feeling confused as to whether or not I made done the right choice. My memories of being a Mormon began surfacing with thoughts such that if I were wrong and had left what was indeed the true church, then I was now an apostate, which gave me no comfort in the eternal scheme of things. The tension was that while hard to deny the life change brought by Christ I also needed to research and contemplate more. After extensive research I became confident that leaving the LDS faith was a good move. But even if Mormonism were false, then that fact would not in itself make historic Christianity true. Perhaps my new found Christian faith was just another deception. After all, I had been deceived once before. How was I to know that the Bible was God's Word or that God even exists? How could I know that some other major world religion was not correct, if any at all? Many thoughts like this shook my faith and caused me to dig deep and wide. Consequently, I developed a love for the truth, something that would shape the rest of my life.

At age 21, I married a wonderful woman who blessed me with three amazing children and has encouraged my relationship with Christ for the last 25 years. My faith in Christ inspired a pursuit of knowledge, knowledge of God and knowledge of how to communicate the truth and goodness of God to others. I went on to finish Bible college, entered pastoral ministry for several years, completed three masters degrees and even made a second effort to finally complete a PhD. During that time I taught at multiple universities and was a campus minister for several years. God has given me a vision for Christ in the academy. Today, I see this as one of the most strategic ways to present the truth of the Gospel to the world. By God's grace, I now have the honor of serving Him to that end by leading a robust campus ministry, Ratio Christi.
