A short demonstration regarding commitment could play out like this. Ask for a volunteer to come and stand in front of the room. When she is standing next to the teacher another student (predetermined before class) could ask her to move. Of course the volunteer will move. Then the teacher could ask her to stand again in her original spot and this time tell her whatever happens please do not move. Another student could ask her to move but this time the volunteer will not budge. What is the difference?
In the first case, the volunteer didn’t realize what the goal was so she was willing to obey another request. In the second, she knew the goal and stood firm because she was committed to achieving the goal.
A simple object lesson but the point is if we decide ahead of time where we want our heart to be then our feet and hands (and the rest of us) will follow. Decide during the calm what we will believe in the midst of the storm because all of us will find ourselves in a storm at some point. But if we already have our route marked we will be able to weather the storm.
