To one he gave five talents, to another two, and to another one, each according to his ability. Then he went on his journey.- Matthew 25:15
This parable gives an account of how a man set out on a journey and gave authority to his servants. It offers insight into some sound business practices from a biblical perspective. The man is also known as the master of these servants in the context of this parable. Look at how this man distributed and delegated among his servants.
You delegate authority to those who have demonstrated the ability to handle it. You may want to start off small, using minor tasks before moving on to larger matters. You just need to ensure that everyone has a grasp of what needs to be done and how it needs to be done.
