The sweetest singer of all was King David of Israel. His life was filled with untold pain and suffering. Persecution, betrayal, personal tragedy — he experienced it all, but he never ceased singing and creating psalms.
David composed psalms for every life situation so that, with a song, he might prune away the poisonous effects of greed, jealousy, fear, anger, depression, and worry. There is no torment or pain that David did not experience, but he triumphed over it all with his psalms . . .
