Three days after the greatest miracle in their history, Israel finds bitter water and starts grumbling. Faith, it turns out, does not run on Tuesday's memories. It needs today's bread.

So God invents a food that spoils overnight, on purpose. Manna could not be stockpiled; it could only be trusted for. Come hungry today, in the good way.

Manna had a shelf life of one sunrise because God was teaching a rhythm, not just running a kitchen. Yesterday's provision, however glorious, cannot be eaten today. The sea had barely closed and Israel was grumbling, because memory without morning trust curdles fast.

David found the answer manna points to: one thing I ask, dwelling with the LORD Himself, daily, gazing. Make your faith a morning practice this week, today's portion of Scripture, today's honest prayer, today's obedience. He is not the God of the dead but of the living, and living things eat every day.
