Moses and Israel's chosen men ascend Mount Sinai, where Moses will receive the stone tablets. The Lord calls Moses and Joshua to proceed further up, where they enter the midst of a great cloud. Moses remains on the mountain forty days, fasting throughout. We begin by considering the mysterious nature of God (the Father), whom no man has ever seen. We then turn to Moses' extraordinary commitment to fasting, an indication of his utter reliance on God. We conclude by taking a fresh look at what Jesus taught regarding the role fasting should have in the lives of Christians. Warning: this lesson might disrupt your eating habits!
