In this sermon Corn In Egypt, God wants tp give us the demonstration of the gifts. God in His wisdom made the outward world in a way that it's a beautiful reflection of the inner world. We're wired in a way that we can always see a truth much better when it's accompanied by a picture.  God wants to take it a step further and give us the demonstration of the gifts! If you tell somebody a simple truth, it is much easier to get your point across when you tell it in or with an illustration.

Nature and grace have some interesting correlations.  The incredible things that the Lord does within the hearts of people, each wonder finds a parallel, a picture, and a correlation with the wonders that God performs in external circumstances.
