The biggest worry some people have about spiritual growth and healing is that they will have to do something they don't like. It is as if the healing process itself is a form of punishment.
When you take a shower, you must sometimes endure changing water temperatures (too hot or too cold), soap in your eyes and wet drippy hair. Is showering a punishment?
Of course not, it is a means to getting clean. You put up with the little discomforts because you have faith that the end result is desirable.
Spiritual healing is like a shower on the inside.
There may be little or big discomforts, but you persevere because Spirit has a wonderful squeaky clean end result planned.
Don't jump out of the shower while you're still soapy. It gets better!
