David and his army commanders then appointed men from the families of Asaph, Heman, and Jeduthun to proclaim God's messages to the accompaniment of harps, lyres and cymbals. (1 Chronicles 25:1)
Forgetfulness -- it plagues us all. Have you been embarrassed lately by meeting an old friend and not remembering his name? Yes, it happens to the best of us. As we get older our memory difficulties increase. When we reach 55 -- we call them "senior moments."
David devised a way for his people to remember God's messages. He appointed men to put the messages into musical lyrics. It may seem weird, but putting Scriputre to music makes remembering easier. We can sing Bible verses over and over until they become part of us. No wonder so many of the Psalms were sung!
Try listening to worship music as you work around the house or drive back and forth to work. Guess what? While you are humming or singing God's words, you are worshipping Him.
