EXODUS 16:4
"I will cause food to fall like rain from the sky for all of you. Every day the people must go out and gather what they need for that day."
God liberated his children from slavery and created a path through through the sea. He gave them a cloud to follow in the day and a fire to see at night. And he gave them food. He met their most basic need: He filled their bellies.
Each morning the manna came. Each evening the quail appeared. "Trust me. Trust me and I will give you what you need." The people were told to take just enough for one day. Their needs would be met, one day at a time.
"Just take enough for today," was God's message. "Let me worry about tomorrow."
