Once when my son was about three years old he had spent about an hour building an incredible duplo block creation. His little sister crawled over and began to pull at his buildings. He exploded with anger and frustration. When I mentioned that it was time for lunch and therefore clean up time which meant taking his building down and putting it away he was beside himself with anger and rage. I sat on the floor with my son trying to help him understand that God desires for us to give ourselves to work and creativity, and to also let go of that which we create. It is so tempting in this life to cling to physical things we can see, touch, and experience. God longs to give us a godly perspective of our life. If we come to him we will have right thinking in regards to the way we invest ourselves.
