Jesus' parable of the goodman of the house hiring workers to work the field at various times during the harvest period is a great explanation of how the kingdom of God is NOT like the hierarchical system we know here on earth. In this spiritual kingdom, anyone who desires to be great must be a servant to all. That flies in the face of what we are accustomed to here on this planet. Many people, even professing Christians, claim that their greatness requires others to serve and dote on them, to offer them money, gifts, special treatment and the like. There can be nothing further from the truth when it comes to God's kingdom.
Jesus is the prime example of the master, king, son, and heir being servant to all. Regardless of when one comes into the kingdom, he or she becomes a child of God with the FULL rights and authorities that come with that status - immediately! Those who have labored and done good works in this world under religious systems are upset when they hear this, because they believe their righteousness is a reward for all of their goodness. The reality is that there is no reward for goodness - only a reward for BELIEVING in the goodness that was done by Jesus on the cross. This is a total paradigm shift from the norm under the Mosaic temple system of the Old Covenant!
