This second volume on Moses' life continues the theme (from volume 1) of serving the Lord. After all, Moses was one of the greatest servants of God in all the Bible. But also, there are many lessons here on growing deeper in your relationship with God, especially through difficult circumstances (such as trying to lead a bunch of grumbling people for 40 years in a barren desert). So whether you're a leader or not, the life of Moses contains many helpful lessons on walking with God.
