A Simple Gospel?

In Searching for God Knows What, Donald Miller wrestles with gospel tracts based on the Four Spiritual Laws. Being an evangelical, Miller lines up along side those who use these tracts and he values them, but he isn't unaware of their limitation. Miller writes:

While the ideas presented in these pamphlets are certainly true, it struck me how simply we had begun to explain the ideas, not only how simply, but how non-relationally, how propositionally. ... The greater trouble with these reduced ideas is that modern evangelical culture is so accustomed to this summation that it is difficult for us to see the gospel as anything other than a list of true statements with which a person must agree.

It makes me wonder if, because of this reduced version of the claims of Christ, we believe the gospel is easy to understand, a simple mental exercise, not in the least bit mysterious.

This is something like what I would like to have said a few months ago when I complained about what is wrong with the Four Spiritual Laws.
