By the close of the book of Genesis, God had chosen a small, insignificant people to become a teaching nation. He wanted to raise up a people who would be living examples of his goodness to the heathen world. So, to bring about such a testimony, God took his people into places that were beyond their control. He isolated Israel in a wilderness, where he alone would be their only source of life, caring for their every need.
Israel had no control over their survival in that desolate place. They couldn’t control the availability of food or water. They couldn’t control their destination, as they had no compasses or maps. How would they eat and drink? Which direction would they go? And where would they end up?
God would do it all for them. He would guide them every day by a miracle cloud, one that glowed at night and dispelled the darkness before them. He would feed them with angels’ food from heaven and provide them with water from a rock. Yes, every single need would be supplied by the Lord, and no enemy would be able to defeat them.
“Out of heaven he made thee [Israel] to hear his voice, that he might instruct thee” (Deuteronomy 4:36). God’s people would hear his very words guiding them, and in turn they would testify, “Who is there of all mankind who has heard the voice of the living God?” (see 4:32-34).
The nations surrounding ancient Israel were filled with “other gods,” idols made of wood, silver and gold. These gods were mute, unable to see or hear, unable to love, guide or protect the people who worshipped them. Yet any one of the nations could look to Israel and see a special people whom God carried through a terrible wilderness. They would see a God who spoke to his people, who loved and felt, who answered prayers and provided miracles. Here was a living God, one who guided his people in every detail of their lives.
God raised up a people who would be trained by him. There had to be a people who lived under his authority, who would trust him completely, giving him full control of every aspect of their lives. That people would become his testimony to the world.
Why would God want full control of a people and insist on their complete trust at all times? It was because only God knew the way and he would perform the impossible that was needed to get them there.
