Chapter 9: holding loosely to the ministry position
No calling of position is permanent in our life and we will never know the day that some of them end. The author tells a story of his friend Kenneth being such a part of worshipping at his church, that he was hired as the main leader after serving for so long. But eventually, his own Pastor did certain things that Kenneth could not agree with, and so with the strength to give up his own life calling and passion; retired from the worship ministry. Another example was when a woman named Cindy was told that she would be stepping down after serving for 20 years, and that she would be a mentor to the new worship leader. He did not want her help, so out of frustration she left ministry all together as well. Ministry however is temporary, but God is what's permanent above ALL else in our lives. We should not cling to our positions in worship, we are called to stand by god no matter where He puts us.
I believe this situation is a lesson to all worshippers, we may not know when we are gonna step down from ministry. However, while we are in ministry we are called to serve GOD wholeheartedly, not  simply WORSHIPPING with our entire being; the purpose is not the position, but who we are worshipping. We mustn't become obsessed with the idea of our position, but with the purpose of why we are where we are.
