From C Michael Patton’s Why Arminianism Won’t Preach (And Calvinism Won’t Sell):

Think about the major conferences out there that are theological in nature: Desiring God, Together for the Gospel, The Gospel Coalition, and Ligonier Ministries. All of them fill churches and arenas with thousands of people. Passion fills the air as speakers talk about theological issues in the church. John Piper, Don Carson, R.C. Sproul, John MacArthur, Albert Mohler, Tim Keller, and the like are invited to speak. Diversity runs deep in these theology conferences. Dispensationalist and Covenant Theologians, paedobaptists and credo baptists, charismatics and non-charismatics, and premillenialists and amillenialists are all represented. However, it is hard to find an Arminian invited to (much less putting together) such engagements. Why? I don’t know, but I suspect that it is because Arminianism, as a theological distinctive, just does not preach. Don’t get me wrong. I did not say that Arminians can’tpreach. They most certainly can. And I did not say that Arminianism is not true (this is not the question on the table). It is simply that the distinctives of Arminianism do not ignite passions in such settings. Evangelicals love to hear about the sovereignty of God, the glory of God in suffering, the security of God’s grace, the providence of God over missions, and yes, even the utter depravity of man. This stuff preaches. This stuff sells tickets.

For the Arminian to put together a distinctive conference, things would be a bit less provocative. Things like “The Responsibility of Man in Suffering,” “Man’s Role in Salvation,” or “The Insecurity of Salvation” won’t preach too well. Think about how hard it is for a Calvinist to try to plug in a token Arminian at a general theology conference. On what subject do you let them speak? “Roger Olson, I would like you to come to our conference and speak on . . . (papers ruffling) . . . ummm . . . (papers ruffling more) . . . Do you do anything in apologetics (except suffering)?”
