Moses is tending sheep, minding his own business, forty years into a quiet exile—and then a bush won't stop burning. As adults we often build lives around comfort and predictability; this sermon confronts what happens when God interrupts our routines with a calling we didn't ask for, and examines Moses' excuses ('I'm not qualified,' 'I'm not a good speaker,' 'send someone else') as the same excuses we still use today.
