These are the inheritances that Eleazar the priest and Joshua the son of Nun and the heads of the fathers' houses of the tribes of the people of Israel distributed by lot at Shiloh before the Lord, at the entrance of the tent of meeting. So they finished dividing the land.
And with this notation Israel had officially moved in to the Promised Land. Now the promises of the covenant relating to Canaan have been kept. God fought for His people and the land was theirs just as He had covenanted with their fathers. God keeps His Word and Joshua's generation lived in that wonderful time of fulfilled promise. They were the people who saw that God had given them everything they had.
God does not lie. He keeps His Word and we can see this in scripture. So Christians have a faithful record that lets us know we can trust God today. When we believe Christ for eternal salvation it is because He has kept His Word in the past. When we hope for Christ's kingdom, we do so convinced that God does not lie or offer vain promises. When we see His future plan for Israel in scripture, we are confident there is still a land and a possession for them as well as for all of us who now follow the Messiah.
And so God is trustworthy. He will provide for us. He will never leave us. He keeps His covenants.
