Why bring in this new terminology of Christian Hedonism. It's a good question. Here's my answer. We live in a superficially Christianized society where thousands of lost people think they do believe in Jesus. Drunks on the street say they do .
Unmarried couples sleeping together say they do.
Elderly people who haven't sought worship or fellowship for forty years say they do. Every stripe of world-loving church attendees say they do. My responsibility as a preacher of the gospel and a teacher of the church is not just to repeat precious Biblical sentences, but to speak the truth of those sentences in a way that will prick the conscience of the hearer and help you feel your need for Christ. What I am trying to do is take a neglected and essential teaching of Scripture and make it as pointed as I can in the hope that some hearts will be stabbed broad awake. And therefore I say, when a person is converted to Jesus Christ that person is made into a Christian Hedonist.
