When considering what it means to know God, many Christians instinctively turn to the life of Moses. Moses was a man who knew God in a deeply personal way, and the book of Exodus is a good place to start for anyone yearning to know God better. Forty Days on the Mountain is a collection of meditations on how God revealed himself to Moses and how Moses responded and related to Almighty God. These readings are brief but profound and can be read in forty consecutive days or spread out to allow more time for reflection. Each reading is more than a casual 'thought for the day'; each is one component in this close examination of what it is to know God. Themes include the necessity of obeying God, the ugliness of sin, the power of bold intercessory prayer, and God's eternal glory.
