In Matthew 20:1-16 Jesus describes the Kingdom of God. It is the famous “The last shall be first and the first shall be last” parable. Jesus talks about a vineyard owner who hires workers throughout the day and yet he pays them the same for differing hours of service.
My wife and my former Pastor have served Jesus since they were young. I have served Him since I was 27. Others serve him literally one hour before they die. We are all equal in the Kingdom of God. The only hierarchy is the inverted one. We can all choose to be the top by choosing to be a servant to all (Just as Jesus does). God’s character is then complete in us.
