Think of your worship team process as the way to accomplish your purpose. For us, this broke down to three steps. We are able to repeat this easily in our communications and recruiting efforts.
What are the things you will do to accomplish your purpose? This has other applications beyond worship teams. Gather your team to help you and use your imagination - this is a great team building exercise!
Team members are expected to fulfill spiritual obligations by growing in Christ, maintaining good interpersonal relationships, worshiping individually and practicing kindness to all.
