Third, I did not ignore the passage. I did mention it but I deliberately did not address it in any detail--in your question in that post--to see how you would respond. And you responded like I thought you would.
And in Luke 7:29,30, it is again taken out of context & also ignores the rest of the testimony of Scripture, such as Acts 15. Let Scripture interpret Scripture. The best commentary on the Bible is the Bible.
Here is the isolated text you referred to, in its full context:
Luke 7:18-50 And the disciples of John shewed him of all these things. And John calling
unto him two of his disciples sent
them to Jesus, saying, Art Thou He that should come? or look we for another? When the men were come unto Him, they said, John Baptist hath sent us unto Thee, saying, Art thou He that should come? or look we for another?
21And in that same hour he cured many of
their infirmities & plagues, & of evil spirits & unto many
that were blind He gave sight.
22Then Jesus answering said unto them, Go your way & tell John what things ye have seen & heard;
how that the blind see, the lame walk, the lepers are cleansed, the deaf hear, the dead are raised, TO THE POOR THE GOSPEL IS PREACHED.
23And blessed is
he, whosoever shall not be offended in Me.
Matthew 11:7-19;
Luke 1:5-25;
Luke 16:14-17)
24And when the messengers of John were departed, he began to speak unto the people concerning John, What went ye out into the wilderness for to see? A reed shaken with the wind?
25But what went ye out for to see? A man clothed in soft raiment? Behold, they which are gorgeously apparelled & live delicately, are in kings' courts.
26But what went ye out for to see? A prophet? Yea, I say unto you & much more than a prophet.
27This is
he, of whom it is written, Behold, I send my messenger before Thy face, which shall prepare Thy way before Thee.
28For I say unto you, Among those that are born of women there is not a greater prophet than John the Baptist: but he that is least in the kingdom of God is greater than he.
29And all the people that heard
him & the publicans, justified God, being baptized with the baptism of John.
30But the Pharisees & lawyers rejected the counsel of God against themselves, being not baptized of him.
31And the Lord said, Whereunto then shall I liken the men of this generation? And to what are they like?
32They are like unto children sitting in the marketplace & calling one to another & saying, We have piped unto you & ye have not danced; we have mourned to you & ye have not wept.
33For John the Baptist came neither eating bread nor drinking wine & ye say, He hath a devil.
34The Son of man is come eating & drinking; & ye say, Behold a gluttonous man & a winebibber, a friend of publicans & sinners!
35But WISDOM is justified of all her children.
36And one of the Pharisees desired Him that He would eat with him. And He went into the Pharisee's house & sat down to meat.
37And, behold, a woman in the city, which was a sinner, when she knew that
Jesus sat at meat in the Pharisee's house, brought an alabaster box of ointment & stood at His feet behind
him weeping & began to wash his feet with tears & did wipe
them with the hairs of her head & kissed His feet & anointed
them with the ointment.
39Now when the Pharisee which had bidden Him saw
it, he spake within himself, saying, This man, if He were a prophet, would have known who & what manner of woman
this is that toucheth Him: for she is a sinner.
40And Jesus answering said unto him, Simon, I have somewhat to say unto thee. And he saith, Master, say on. There was a certain creditor which had two debtors: the one owed 500 pence & the other fifty.
42And when they had nothing to pay, he frankly forgave them both. Tell me therefore, which of them will love him most? Simon answered & said, I suppose that
he, to whom he forgave most. And he said unto him, Thou hast rightly judged.
44And he turned to the woman & said unto Simon, Seest thou this woman? I entered into thine house, thou gavest me no water for my feet: but she hath washed my feet with tears & wiped
them with the hairs of her head.
45Thou gavest me no kiss: but this woman since the time I came in hath not ceased to kiss my feet.
46My head with oil thou didst not anoint: but this woman hath anointed my feet with ointment.
47Wherefore I say unto thee, Her sins, which are many, ARE FORGIVEN; for she loved much: but to whom little is forgiven,
the same loveth little.
48And he said unto her, Thy sins ARE forgiven.
49And they that sat at meat with him began to say within themselves, Who is this that forgiveth sins also?
50And he said to the woman, THY FAITH HAS SAVED THEE; GO IN PEACE.
In the context, the first section (vs 18-23) Jesus answers the disciples of John & in the context says that the gospel is preached to the poor. Nowhere there does Jesus, in preaching the gospel & healing Jewish people, state the baptism of John nor Jesus & His disciples baptizing people who believed in Jesus as NECESSARY AS A REQUIREMENT (according to your definition) TO BE SAVED FOR JEWISH PEOPLE.
In the next part of the context (vss 24-28), Jesus describes the ministry of John the Baptist, its purpose & who he is. Again no mention of John's baptism as necessary, as a requirement for Jewish believers in the Messiah--must do--in order to be saved. If it was vital for their salvation, Jesus would have taught so in both of these contextual sections.
John preached faith in the Messiah, predicted to come & now had come. He prepared the way of YHWH, which is Jesus, for the people to believe in Him. His was a message of preparation for the Jewish people, to prepare their hearts to believe in the Messiah for forgiveness & salvation.
Now we come to the isolated verses--you say--proves that John's baptism was necessary, was required, to save Jewish believers & without it, they could not be saved. But they are in a section of the context that goes from vs 29 to 35, so I will address this immediate context.
Simply reading what the Scripture actually SAYS, it says that all those in the crowd, including publicans, that had been baptized with the baptism of John JUSTIFIED GOD. It does NOT say, justified BY GOD, which directly has to do with salvation.
In CONTEXT, these Jewish people listening TO JESUS TEACHING about John & the purpose of his ministry. They were AGREEING with Jesus' teaching & thus JUSTIFIED GOD, that this ministry of John was confirming God's righteous message through him.
Again no mention--in this contextual section--is made that John's baptism or even Jesus' disciples water baptizing Jews is necessary, is a vital requirement, for them to be saved & without it they could not be saved.
And in vs 30, it DOES NOT SAY that the Pharisees & the lawyers were not saved because they rejected John's baptism, but that they rejected the counsel of God against themselves, that pointed to the Messiah being the the Savior of the world & that belief in Him saves them.
John the Baptist warned them at that time, when they refused to be baptized by him, of fleeing from the wrath of God that would come for rejecting his MESSAGE that prepared people to meet their God & turn to Him to be saved & forgiven of their sins.
They were ALREADY LOST, so it wasn't a matter of losing their salvation if they didn't receive John's baptism, because they had no salvation with which to begin!
And later in Matt 23, Jesus then warns them that after 2 years of ministering with John the Baptist gone, they were now at the point of not escaping the wrath of God coming. They had further progressed in their UNBELIEF.
And the final section of the context in Luke 7 is that of the woman who anointed Jesus' with the precious ointment, cleaning his feet with her tears & hair. This is an example of such humility that is rare. She apparently was one that was not of the Jewish crowd that had received John's baptism but someone new.
Again it has much to teach us but again, Jesus never required this Jewish woman to be water baptized in order to be saved. But what did save this Jewish woman IN THE GOSPELS? It was her great love & humility & her faith in Jesus that saved this woman. She loved Jesus. She served Jesus. She truly anointed Him as the Messiah & in anticipation of Christ's coming death. Her faith in Jesus is what saved her not any water baptism, as Jesus directly said.
And he said unto her, "Thy sins ARE forgiven." And they that sat at meat with him began to say within themselves, Who is this that forgiveth sins also? And he said to the woman, "Thy faith has saved thee, GO in peace."
Jesus did not say, Go & be baptized in water. He said it was her faith that saved her & because of her love for Jesus, willing to receive the ridicule of others for what she did, her sins, which were many, WERE FORGIVEN by Christ Himself. No works were mentioned as saving her; only her faith & her love & humbling herself before the Lord. God gives GRACE to the humble (James 4:6; I Pet 5:5) but opposes the proud.
