Nehemiah went from cupbearer (which, by the way, was a very “cush insider” job) to construction manager to governor. Talk about distinct phases.
Just because God has called you to a specific role doesn’t mean you are to stay in it forever. There are seasons for everything. Sometimes He will call you to narrow your role and other times He will move you to a totally different function or role–often to keep you trusting in Him. When we get in trouble is when you confuse method with mission. God generally calls us to a life mission and the method or role we play can change dramatically. Often we sense our calling is primarily to a certain method or role and we get inflexible and box ourselves, and God, into a presupposition of the same ol’ same ol’.
Example: Phil Vischer used the method of Veggie Tales to accomplish his life mission of reaching people creatively with the hope of God. Veggie Tales came crashing down but he wasn’t devastated or out of the game because he still had his life mission. The method was just going to change.
How open are you to God saying, “You life mission is the same but how you go about it is going to be totally different than how you approached it in the past?” Will you step out or say, “No thanks, God, I like being a cupbearer. It is what I know, I am good at it, and most importantly it is certain and safe for me.” How open are you?
