This booklet was written in 1967 and is a critique of what he calls “the invitation system” in evangelism. What Murray means by this is altar calls and inviting people to come forward and pray a prayer. I read it because after reading Naselli’s *No Quick Fix*, I wanted to see a little more in the history of altar calls.
In the booklet, Murray addresses the idea of altar calls from three angles. First, biblically. Second, psychologically. Third, concerning its visual effects. In each of these, I think he does a superb job giving wisdom and discernment on the issue.
Throughout the booklet, his main example is Billy Graham. He admits there are many more, but he chooses Graham because he was the most popular proponent of the movement. Murray does a good job not being overly critical and harsh of Graham, but pointing out areas in his invitation system that can lead to error and confusion.
That was the short booklet/essay. It was well organized and argued.
But to my surprise, what was the best part of the book was the last 10 pages or so of quotes from various preachers/teachers from the past that applied to the subject. In here were some excellent quotes from Puritans, Spurgeon, Lloyd Jones and more that all applied to the idea of the altar call. Even if someone is more lenient toward the altar call and invitation system than Murray is, I still encourage them to read his essay, and especially read the quotes from these men that almost everyone respects.
Overall, I agreed with most of what Murray said, although I wish he fleshed it out more in a longer work. The booklet was not only a helpful tool in discernment, but helped me understand more of what was going on at the crusades and invitations.
