God wants us to live in daily dependence on Him. Israel was given manna to sustain them in the wilderness, but he set it up so they would need to go out and gather it day by day. If too much was gathered, it went bad. If they waited too long, the sun melted it. Israel was pushed into a situation where they needed to seek life from their God each and every day, and they had to be prompt about it.
What does this tell us about our walk with God? We desperately need God in our lives, and it has to be regular and prompt! May we go out each day, receiving what we need from Him to live and stay faithful!
