It is the same way with our spiritual life, no? There is always a lot to do in the field of the kingdom. Lots of people and situations need daily attention. But if I don't pull back on a daily basis and rest my soul in prayer, it will become injured, due to neglect. Then I will go out to do my work/ministry attend to daily tasks, but I will do them with some irritability, resentment, or overall bad mood. Of course, the job will be done poorly, and people might wish me to go away and have my fit of discontent elsewhere.
So it is best to let the world go on without my attention for a while each day while I attend to the health of my soul.
