A shrewd person grasps a critical situation with resolution and foresight. Jesus is concerned here with something more critical than a financial crisis. His concern is that we avert spiritual crisis through the exercise of faith and foresight. If Christians would only expend as much foresight and energy to spiritual matters which have eternal consequences as much as they do to earthly matters which have temporal consequences, then they would be truly better off, both in this life and in the age to come. True wealth consists not in what we keep but in what we give away.
Possessions are a great responsibility.
The Lord expects us to use them honestly and responsibly and to put them at his service and the service of others. We are God's servants and all that we have belongs to him. He expects us to make a good return on what he gives us. God loves generosity and he gives liberally to those who share his gifts with others. The Pharisees, however, had no room for God or others in their hearts.
