Joshua 21:43-45 is the key text in that book because at this point that Joshua can say that God gave everything that had been promised. With the settling of the land, the land promise made to Abraham was now fulfilled. Israel was not fully a nation after becoming a people and having law, but now they are. Notice the facets of God’s promise to them.
“So the Lord gave Israel all the land which He had sworn to give to their Fathers” (43). God gave them physical blessings. They owned and called home the land God promised their ancestors.
“The Lord gave them rest on every side” (44). He gave them emotional blessings. This was a long time in coming for these battle-weary warriors. The anxiety of being the underdog, of facing frightening foes, all of that (at least for now) was behind them.
“No one of all their enemies stood before them; the Lord gave all their enemies into their hand” (44). He gave them spiritual blessings. These idolaters and heathen people could not stand before them and the Lord dispossessed them, giving them into the hands of His chosen people.
No wonder this summary statement is made: “Not one of the good promises which the Lord had made to the house of Israel failed; all came to pass” (45). This was the God of Joshua. It’s also the God of us.
This text shows us how comprehensively God blessed the lives of His children. These verses speak of a material inheritance. Even if it is the choicest spot on the globe, it cannot compare to what God will give to His faithful. Let’s rejoice in the hope Peter shares, regarding the promise of His coming (2 Pet. 3:4). He writes, “But the day of the Lord will come like a thief, in which the heavens will pass away with a roar and the elements will be destroyed with intense heat, and the earth and its works will be burned up. Since all these things are to be destroyed in this way, what sort of people ought you to be in holy conduct and godliness, looking for and hastening the coming of the day of God, because of which the heavens will be destroyed by burning, and the elements will melt with intense heat! But according to His promise we are looking for new heavens and a new earth, in which righteousness dwells” (2 Pet. 3:10-14).
