We read the story of God providing the manna to the Children of Israel in Exodus 16. As I was reading this passage, I was struck with the idea that this manna represents the grace of God. The manna was 100% from God. The manna was provided to everyone without discrimination. The manna was easily accessible to all (right outside their door). All anyone had to do was walk outside and gather the manna. God provided it, they had to go out and get it to benefit from it. God made the provision and man acted upon that provision in obedience to God's commands.
