"But the Augustinian perspective tells us that they can do this only once we can do this only once our desires have already been changed enough that we want to engage in the practice. No one will develop a transformative and durable new practice of prayer unless they fundamentally want to and want to in such a way that they'll overcome the times when it's harder. But in another way, the reason so many attempts to change ourselves and others to spiritual disciplines actually founder is because the core desire isn't yet there. As Jesus told us, you have to change the tree first and the fruit will follow. The focus on the heart and the practices will follow. The focus on the practices alone and we're back to the brick wall again. "
