Did you know that singing not only can boost your mood, but also alleviate anxiety and stress? David knew all about anxiety. Constantly chased by his enemies and a king who wanted him dead, the book of Psalms is filled with the cries of David for deliverance. But even when it seemed hopeless, he never gave up, never gave in to despair. Instead David remembered the promises of his Father in heaven, and trusted in His goodness. And from a heart filled with joy, sang songs of praise to God for His love and faithfulness.
