When the disciples came to Jesus and asked, "Lord, increase our faith" He gives them the example of a servant who works all day and when He comes in from the field the Master expects him to serve in the kitchen too. And after all that he has only done what was expected of him.
When you think of faith, do you also think of obedience? When you think of the phrase, 'Well done, good and faithful servant', what do you think that servant has accomplished?
