"Christian joy is a deep experience of adequacy and confidence in spite of the circumstances around us. The Christian can be joyful even in the midst of pain and suffering. This kind of joy is not a thermometer but a thermostat. Instead of rising and falling with the circumstances, it determines the spiritual temperature of the circumstances. Paul put it beautifully when he wrote, "I have learned, in whatsoever state I am, therewith to be content" (Phil. 4:11)."
