A true honest question. Didn't the Jewish nation start with Abraham? God asked Abraham to circumcise himself, his family males and then his whole male household servants and all as a covenant with God? Then Isaac would have been first born Jew?
I feel that once this question is answered then I could have a better shot at thinking about how I would answer the thread question. Sometimes even Blonds think...lol
Thanks for bringing the thread back on track. There was a dispute about whether Paul received the revelation of the mystery first (being the inclusion of the Gentiles into salvation) or did it come from the Jews first before the Gentiles that Paul was called to minister.
Jesus teaching His disciples in Mark 4:11 "And he said unto them, Unto you it is given to
know the mystery of the kingdom of God: but unto them that are without, all these things are done in parables:"
The other thing that is obvious was that Peter was the first one to understand the inclusion of the Gentile with the Jews. Jesus ministered about this mystery of the kingdom to the 12 disciples, but Peter didn't comprehend that the Gentiles were included until his vision of all the unclean animals on the sheet from heaven until God said what He had made clean was clean. Then Peter went to Cornelius (a Gentile) in acts chapter 10. So we can see that the mystery of the kingdom had now been revealed to both the Jew and the Gentile before Paul's conversion.
Acts 10:44-48 and Acts 11:1
"While Peter yet spake these words, the Holy Ghost fell on all them which heard the word. And they of the circumcision which believed were astonished , as many as came with Peter, because that
on the Gentiles also was poured out the gift of the Holy Ghost. For they heard them speak with tongues, and magnify God. Then answered Peter,
Can any man forbid water, that these should not be baptized, which have received the Holy Ghost as well as we? And he commanded them to be baptized in the name of the Lord. Then prayed they him to tarry certain days. And the apostles and brethren that were in Judaea heard that
the Gentiles had also received the word of God.
The only thing Paul was told right after His conversion by Ananias was what he would have to suffer for the Lord's sake, but he also was enlightened of the spiritual truth in the law and the prophets, for he had studied those things long before he was blinded on the road to Damascus. This understanding enabled him to minister to the Gentiles proving Christ as the true Messiah and Savior to the world via this understanding of the Old Testament scriptures available at the time. We can see by Paul's writings to the Romans that the mystery was (and is) the plan of salvation through Christ Jesus that was perceived and conceived by God the Father and the Son before creation. Colossians 1:12-20
Romans 16:25-27
25 Now to him that is of power to stablish you according to my gospel, and the preaching of Jesus Christ, according to the revelation of the mystery, which was kept secret since the world began,
26 But now is made manifest , and by the scriptures of the prophets, according to the commandment of the everlasting God, made known to all nations for the obedience of faith:
27 To God only wise, be glory through Jesus Christ for ever. Amen . [Written to the Romans from Corinthus, and sent by Phebe servant of the church at Cenchrea.]
There has been a dispute as to the meaning of the word "mystery" and about who received the ministry of this mystery first. Some say it was Paul first, but the Bible indicates quite vividly that is was Peter instead. At any rate both were Jews.
Some do not want to recognize any Jewish influence within the plan of salvation especially when we begin to recognize the Biblical Hebrew culture of the Old Testament covenant with God. It is evident that there is a clear desire to separate this cultural influence from salvation while at the same time saying that there is no difference between the Jew and the Gentile as Paul said in truth. There will be more disputes because of what I just explained.
