At some military camps across Europe during World War II, an unusual type of supply was air-dropped for homesick soldiers—upright pianos. They were specially manufactured to contain only 10 percent of the normal amount of metal, and they received special water-resistant glue and anti-insect treatments. The pianos were rugged and simple but provided hours of spirit-lifting entertainment for soldiers who gathered around to sing familiar songs of home.

Singing—especially songs of praise—is one way that believers in Jesus can find peace in the battle too. King Jehoshaphat found this to be true when he faced vast invading armies (2 Chronicles 20). Terrified, the king called all the people together for prayer and fasting (vv. 3–4). In response, God told him to lead out soldiers to meet the enemy, promising that they’d “not have to fight this battle” (v. 17). Jehoshaphat believed God and acted in faith. He appointed singers to go ahead of the soldiers and sing praise to God for the victory they believed they would see (v. 21). And as their music began, He miraculously defeated their enemies and saved His people (v. 22).

Victory doesn’t always come when and how we want it to. But we can always proclaim Jesus’ ultimate victory over sin and death that’s already been won for us. We can choose to rest in a spirit of worship even in the middle of a war zone.
