The details of Jacob and Esau’s marriages are all about family heritage and bloodline. I don’t think they neatly apply in the band room. And not too many band directors find themselves on the receiving end of ‘dream-promises.’
However, lots of people make ‘deals’ with God! Sometimes in the middle of a crisis, most often out of desperation, and once in a while, based on inspiration. Jacob was inspired to make a vow after a dream. What has inspired you lately regarding your band program? Did you go to a workshop with actual helpful insights? Have a conversation with a colleague that gave you a fresh perspective? Take your new idea and energy and share it with your people. Give them the resources needed (including your time, expertise and energy), and ask them to work in partnership to grow and strengthen the band.
