LOL! One never knows...
the slam on mysticism, while having some merit, is unfair. Elistism implies a lack of humility. Many mystics are very humble.
Some Christians feel a stronger need for daily devotion than others. That doesn’t make one more Christian than another. So, instead, perhaps those who are more insecure in their own feelings and devotions see those with stronger commitments in elitist terms.
Moreover, this slam on mysticism obscures the reader to the incredibly rich literature of spiritual practices. Some ordinary, some strange, but all directed at working to be a better Christian. We are all sinners, so if we choose to improve ourselves, there are a variety of means available.
Another area of argument is whether salvation is simply handed to you and you cash out when you die, or does salvation carry a responsibility, a duty, to practice what you are taught. And, if you have problems practicing it, there are “exercises” to help you work towards it. That doesn’t make you better, just more diligent.
