CommitmentRead Joshua 22:1-8. What do these verses tell us about the commitment of the Reubenites, the Gadites, and the half tribe of Manasseh?Joshua affirms that the tribes from the other side of the Jordan have fully satisfied the obligations set out by Moses and himself, which meant a significant dedication to, and sacrifice on behalf of, Israel’s common cause. They fought alongside their brothers for “many days,” which in reality meant about six to seven years (compare with Josh. 11:18, Josh. 14:10, Deut. 2:14). Their wives and children were left at home, on the east side of Jordan, yet they decided to fight loyally along with their brothers, facing the threat of injury and death in war.These verses indirectly underline the importance of the unity of the nation and that of the land. They also prepare the way for the ensuing story, which is ultimately about unity. Will the Israelite tribes stay united, despite the strong natural border that the Jordan forms between them? Will they allow geography to set its mark on their national identity, or will they let their common worship of the only God keep them as His chosen nation, united and strong under His theocratic guidance?Joshua explains the only way that such fidelity has been possible: they did not serve their fellow Israelites but Yahweh Himself, who charged them with their mission.We find this same principle in the New Testament. The apostle Paul admonished Christians to render their service as if they were working for God and not only for human beings (see Eph. 6:7, Col. 3:23, 1 Thess. 2:4). What higher calling is there than working for, ultimately, the Creator of the cosmos?In everyday life, we often face challenges and difficulties that can easily discourage us and make us want to give up the fight. That’s easy, at times, to do. Yet we can call upon the power of the Lord, who promises to be with us and enables us to do what He asks of us. If we keep our higher calling before us, we can be motivated to press on ahead, despite the inevitable challenges and discouragements that are part of our fallen existence here.Joshua 22:5-6 reports that Joshua appealed to the departing tribes to remain faithful
