The Israelites in the desert found that hoarded manna rotted. They were permitted no bank accounts and no insurance policies. God is enough. He will be tomorrow who he was today. Later, through Jeremiah (Jeremiah 2:13) God chastises Israel for digging cisterns next to streams of living water, hedging their bets just in case God forgets to be God...or neglects to be good. God is enough. Will he not be tomorrow who he has been today?
