We all want to be happy. So why does the Bible feel the need to command us to be happy? So much so that it is the most often repeated command in all of scripture. If we want it, then why do we need to be told to have it? According to scripture, it's because our joy sensor is broken. We look for joy in things that don't sustain- things that should point us to a bigger, better source of joy. So the Bible repeats the refrain for us to rejoice as a beacon to the true source of deeper, greater joy.
