Adam and Eve were placed in Paradise to work it and take care of it. While still in their perfect state they had work to do. God still gives us work to do as opportunities for meaningful service to him and to our neighbor. We often fail to see work in this way. We tend to prefer idleness. Thankfully Jesus served God and his neighbor perfectly and then paid for our idleness, laziness and discontent by his death in our place on the cross.
