Singing changes the brain! Some studies show that when we sing, our bodies release hormones that relieve anxiety and stress. Other research indicates that when a group of people sings together, their heartbeats actually synchronize with each other.
The apostle Paul’s writing encourages the church to speak to one another with psalms, hymns, and spiritual songs (Eph. 5:19). And the Bible repeats, “Sing praise” more than fifty times.
In 2 Chronicles 20, we read a story of God’s people demonstrating their trust in God by singing as they marched into battle. Enemies were heading toward the people of Judah. Alarmed, King Jehoshaphat called everyone together. He led the community in intense prayer. They didn’t eat or drink, but only prayed, “We don’t know what to do, but our eyes are on you” (v. 12). The next day, they set out. They weren’t led by their fiercest warriors, but by their choir. They believed God’s promise that they would be delivered without having to fight at all (v. 17).
While they sang and walked toward the conflict, their enemies fought each other! By the time God’s people reached the battlefield, the fighting had ended. God saved His people as they marched by faith toward the unknown, singing His praises.
God encourages us to praise Him for good reasons. Whether or not we are marching into battle, praising God has power to change our thoughts, our hearts, and our lives.
