Frank Nelte says: "I believe that the Apostle John had come to understand that "the feeding of the 5000" represents ALL THOSE WHO WILL BE IN THE FIRST RESURRECTION!
And that means that the subsequent "feeding of the 4000" represents ALL THOSE WHO JOIN THE FAMILY OF GOD LATER, AS "THE END ONES"!
When we really understand this correctly, these two "feedings" represent the last two of the three stages by which God builds His Family."
