JC - Chapter 27

In the parable of the Prodigal Son, I believe the most thought provoking of the parable is the elder brother for as he learned his brothers return and the grand celebration -

"...he was angry, and would not go in: therefore came his father out, and intreated him.
29 And he answering said to his father, Lo, these many years do I serve thee, neither transgressed I at any time thy commandment: and yet thou never gavest me a kid, that I might make merry with my friends:
30 But as soon as this thy son was come, which hath devoured thy living with harlots, thou hast killed for him the fatted calf.
31 And he said unto him, Son, thou art ever with me, and all that I have is thine."  (New Testament | Luke 15:28 - 31)

I even note that the brother did not suggest that his own brother had come but said "thy son was come" almost sounding like he felt no claim that this was his brother.  Should not the brother have been just a joyous with the return of his brother as that of the father?

I believe that this parable is more of a chastisement to the Pharisees and to all of us that claim to be His disciples.  We should be joyous when any of God's children repent and return to Him.
