We look at various interpretations of this well-known parable and see what their application might be. Finally, we select the one that seems most to accord with the context in which the parable is found. Jesus was teaching His apostles that, notwithstanding the rewards He had just been teaching them would be theirs, they should not grow proud of their position but rather be humble, since it was His calling that determined their place in His kingdom and He could call others who would get exactly the same reward as they.
From this, we are encouraged to be like our Savior, who humbled Himself to death on a cross. We should not take pride in ourselves, our length of service in a fellowship or any other such thing. We should not resent the salvation that God chooses to bestow on those who have been our enemies but should rejoice in His grace and generosity.
