When you have an open wound, it's important to take the necessary steps to prevent infection. For example, antibiotics are often necessary, as well as wound cleanings and sterile dressings. But you also have to give the wound enough time to heal. You cannot make the healing process go any faster than it needs to. Taking these steps will allow the wound to heal completely, avoiding infection that could make the problem much worse than it was at the beginning.

The same goes for spiritual healing.  While it's important to take all the necessary steps to ensure you are making progress, you also have to give yourself enough time to see a change.
