What did God promise Abraham's descendants concerning land?
God promised that Abraham's descendants would become a nation of people gathered within a specific geographical area, a land that He would give them. He mandated that it would be their land, though they would have to fight battles to possess it.
Les explains that God promised a nation of people coming out of Abraham who would be congregated within a geographical area, a land that would be promised to them. In Joshua 1, after Moses died, God told Joshua to lead the people over the Jordan into the land He was giving them. They would have to fight wars and battles, but God had mandated that it would be their land. Les also references Ezekiel 37's vision of a valley of dry bones, noting that a literal truth is drawn from that vision.
