Abraham and Sarah journey from their home to the place that God promises to them and to their descendants. It is a journey of faith, both because of the physical travel involved, and also because of the way God keeps them on the right spiritual path. Many centuries later, the Apostle Paul writes, “Against all hope, Abraham in hope believed and so became the father of many nations.” How can you be against all hope and also in hope? Abraham, Sarah and later Isaac learn that this is a God thing. And when a child is born, Abraham and Isaac foreshadow how God is going to save His people through the nation built by Abraham’s descendants. God will provide the sacrifice!
