In Exodus, the Lord gave the children of Israel just what they needed when they needed it. He gave them manna to eat when they needed it (they of course thought they needed more) He gave them a cloud by day and fire by night to guide them and tell them when to go and when to stay. God does the same for us. We may not always be mindful of it, and sometimes want more, but God gives us just what we need when we need it. We need to just willingly, and with thankful hearts, take what His gracious hands gives to us.
