This was one of the first ones I answered here, so I won't go through the long version again, but the short version -- God put us in this playground for a reason. He wants us to make the most of it. The meaning of life? Live! Enjoy the toys your Father has given you. Appreciate His gifts. Live a life that makes Him smile to see how much you enjoy and are grateful for what He's put there for you, from a first kiss to a fall day to an inspiring scripture to an old friend to a thunderstorm.
