Norman Shepherd writes in the Call of Grace of the dual dangers of evangelism:
…Reformed pastors want nothing to do with “easy believism.” This is a way of presenting the gospel that separates acceptance of Christ as Savior from acceptance of him as Lord. The Bible teaches that without sanctification, or holiness of life, no one will see the Lord (Heb. 12:14). Therefore, it is not enough to ask the sinner for a simple act of faith. The evangelist must also demand repentance. But the difficulty here is that the opposite of “easy-believism” often turns out to be “hard-work-ism,” and that is not very good news. Indeed, in terms of Paul’s argument in Romans and Galatians, that destroys the gospel (68).
