When the People of God were wandering in the desert, in what the Bible calls "the wilderness", God was directing an entire people toward its earthly home.  But as Christians, we have a personal relationship with God.  We don't have a covenant, like the Old Covenant, between God and all believers; rather, each of us has a personal covenant with God - we are individually led to our spiritual and our eternal home by God.  That is the heart of the New Covenant and the heart of our faith.
