Seeing the existence of an organization of God (appointed to dispense spiritual food at the proper time) in the parable of Mathew 24:45-51 is like trying to discern who the good Samaritan is! Parable of good Samaritan is all about how to be loving toward our neighbors whereas parable of Mathew 24:45-51 is all about alertness as bringing good returns and carelessness as bringing bitter returns [which means everyone should learn from experience].
God’s ways are not like the ways of humans (unlike humans who responds to honor and dishonor, God is least bothered when He is honored or dishonored by humans). That means God would not go for an illogical option of appointing an organization to dispense spiritual food to others because there is no spiritual food that suits everyone. For example, there are many humans suffering in the world; yet suffering is also relative: A kid without much to eat and without a good hygiene in a third world country, may not feel that “experience” as suffering as a kid from the fist world country does. Suffering is only a part of life, yet what about the life itself? For most people, life is a struggle—a fight at many levels whereas for others life is to be enjoyed, relaxed—with nothing to “prove.”
Life has its own ways to teach a person!
