Neither Winman or Bob understand this PARABLE! If you want to understand a parable you must look at the context and see WHO Jesus is speaking to and WHY or WHAT is the circumstance Jesus is addressing.
There are THREE parables all having to do with the very same theme and addressing the very same issue. Look at Luke 15:1-3 to see who he is addressing and why.
1 ¶ Then drew near unto him all the publicans and sinners for to hear him.
2 And the Pharisees and scribes murmured, saying, This man receiveth sinners, and eateth with them.
3 And he spake this parable unto them, saying,
1. He is addressing self-righteous pharisees and scribes - v. 2
2. These parable are addressed to "them" - v. 3
3. The purpose of the parables is to address the self-righteousness Pharisees and scribes who saw themselves better than "publicans and sinners" or saw themselves in NO NEED OF REPENTANCE - v. 1
Now, look at the consistent theme running through all three parables (sheep, coins, two sons).
1. There is one group NEVER LOST (99 sheep, 9 coins, elder son)
2. There is one group in need of repentance, lost, found (1 sheep, 1 coin, 1 younger son).
3. There is one major emphasis in all three, heaven rejoices over the group that knows there lost and repent.
The application is simple and clear! Those whom the Scribes and Pharisees scorned (publicans and sinners) knew they were sinners and knew they were lost and needed repentance (salvation) [lost sheep, lost coin, lost younger son]. However, the other group NEEDED NO REPENTANCE (Scribes and Pharisees) or 99 sheep, 9 coins and older son.
Jesus is addressing those who perceived themselves as BETTER THAN THOU who saw themselves in NO NEED OF REPENTANCE and presented them as such in the parabolic character of the 99 sheep, 9 coins and elder son.
However, in reality there is no such person who can claim "Lo, these many years do I serve thee, neither transgressed I at any time thy commandment:"
Notice there is NO REJOICING and NO FATTED CALF, and NO BRINGING HOME over the 99 sheep, 9 coins and elder son!
Jesus without these parables says it bluntly elsewhere to this same group:
30 But their scribes and Pharisees murmured against his disciples, saying, Why do ye eat and drink with publicans and sinners?
31 And Jesus answering said unto them, They that are whole need not a physician; but they that are sick.
32 I came not to call the righteous, but sinners to repentance.
Remember, he is addressiing ADULTS and the ELDER son is no child and claims to SERVE for MANY YEARS and yet he claims he is absolutely sinless. No such ADULT human exists (apart from Christ) who has SERVED God for "MANY YEARS" and is without need of repentance.
Now neither one of you will except this obvious and clear interpretation of these parables but for those who have eyes to see and ears to hear, let them see and hear!
Baloney, Jesus NEVER even hinted that the scribes and Pharisees were sinless. And I doubt the scribes and Pharisees themselves would claim to be absolutely perfect.
This is what Jesus said about the scribes and Pharisees;
Mat 23:1 Then spake Jesus to the multitude, and to his disciples,
2 Saying, The scribes and the Pharisees sit in Moses' seat:
3 All therefore whatsoever they bid you observe, that observe and do; but do not ye after their works:
for they say, and do not.
4 For they bind heavy burdens and grievous to be borne, and lay them on men's shoulders; but they themselves will not move them with one of their fingers.
5 But all their works they do for to be seen of men: they make broad their phylacteries, and enlarge the borders of their garments,
6 And love the uppermost rooms at feasts, and the chief seats in the synagogues,
7 And greetings in the markets, and to be called of men, Rabbi, Rabbi.
8 But be not ye called Rabbi: for one is your Master, even Christ; and all ye are brethren.
9 And call no man your father upon the earth: for one is your Father, which is in heaven.
10 Neither be ye called masters: for one is your Master, even Christ.
11 But he that is greatest among you shall be your servant.
12 And whosoever shall exalt himself shall be abased; and he that shall humble himself shall be exalted.
13 But woe unto you, scribes and Pharisees,
hypocrites! for ye shut up the kingdom of heaven against men:
for ye neither go in yourselves, neither suffer ye them that are entering to go in.
14 Woe unto you, scribes and Pharisees,
hypocrites! for ye devour widows' houses, and for a pretence make long prayer: therefore ye shall receive the greater damnation.
15 Woe unto you, scribes and Pharisees,
hypocrites! for ye compass sea and land to make one proselyte, and when he is made, ye make him twofold more
the child of hell than yourselves.
16 Woe unto you,
ye blind guides, which say, Whosoever shall swear by the temple, it is nothing; but whosoever shall swear by the gold of the temple, he is a debtor!
17 Ye fools and blind: for whether is greater, the gold, or the temple that sanctifieth the gold?
18 And, Whosoever shall swear by the altar, it is nothing; but whosoever sweareth by the gift that is upon it, he is guilty.
19 Ye fools and blind: for whether is greater, the gift, or the altar that sanctifieth the gift?
20 Whoso therefore shall swear by the altar, sweareth by it, and by all things thereon.
21 And whoso shall swear by the temple, sweareth by it, and by him that dwelleth therein.
22 And he that shall swear by heaven, sweareth by the throne of God, and by him that sitteth thereon.
23 Woe unto you, scribes and Pharisees,
hypocrites! for ye pay tithe of mint and anise and cummin, and have omitted the weightier matters of the law, judgment, mercy, and faith: these ought ye to have done, and not to leave the other undone.
24 Ye blind guides, which strain at a gnat, and swallow a camel.
25 Woe unto you, scribes and Pharisees,
hypocrites! for ye make clean the outside of the cup and of the platter,
but within they are full of extortion and excess.
26 Thou blind Pharisee, cleanse first that which is within the cup and platter, that the outside of them may be clean also.
27 Woe unto you, scribes and Pharisees,
hypocrites! for ye are like unto whited sepulchres, which indeed appear beautiful outward,
but are within full of dead men's bones, and of all uncleanness.
28 Even so ye also outwardly appear righteous unto men,
but within ye are full of hypocrisy and iniquity.
29 Woe unto you, scribes and Pharisees,
hypocrites! because ye build the tombs of the prophets, and garnish the sepulchres of the righteous,
30 And say, If we had been in the days of our fathers, we would not have been partakers with them in the blood of the prophets.
31 Wherefore ye be witnesses unto yourselves, that ye are the children of them which killed the prophets.
32 Fill ye up then the measure of your fathers.
33 Ye serpents, ye generation of vipers, how can ye escape the damnation of hell?
34 Wherefore, behold, I send unto you prophets, and wise men, and scribes: and some of them ye shall kill and crucify; and some of them shall ye scourge in your synagogues, and persecute them from city to city:
35 That upon you may come all the righteous blood shed upon the earth, from the blood of righteous Abel unto the blood of Zacharias son of Barachias, whom ye slew between the temple and the altar.
36 Verily I say unto you, All these things shall come upon this generation.
37 O Jerusalem, Jerusalem, thou that killest the prophets, and stonest them which are sent unto thee, how often would I have gathered thy children together, even as a hen gathereth her chickens under her wings, and ye would not!
38 Behold, your house is left unto you desolate.
39 For I say unto you, Ye shall not see me henceforth, till ye shall say, Blessed is he that cometh in the name of the Lord.
Jesus condemned the scribes and Pharisees in the most harsh fashion, and now you want us to believe he is telling them they are sinless?
Nice attempt to explain away scripture that totally destroys Calvinism, but no gold ring for you.
