BobY777: Jesus revealed to Paul the gospel of the Grace of God over 3 years in the Arabian desert. After this revelation, did Paul preach a Kingdom gospel to the Jews and a Grace gospel to gentiles? And later he switched over to preaching a grace gospel to both Jews and gentiles?
JL: Speaking of Paul in [Acts9:13 Then Ananias answered, Lord, I have heard by many of this man, how much evil he hath done to thy saints at Jerusalem:14 And here he hath authority from the chief priests to bind all that call on thy name. 15 But the Lord said unto him, Go thy way: for he is a chosen vessel unto me, to bear my name before the Gentiles and kings, and the children of Israel:]
Christ said Paul was chosen to bear His name before Gentiles, kings and the children of Israel. My understanding Paul received the one and only gospel of Jesus Christ at his vision on the way to Damascus. The same gospel Jesus taught to the other apostles. Paul then went for three years to Arabia most likely to meditate on the OT in light of Christ’s revelations and perhaps how to present that one gospel to Gentiles. He had no problem presenting it to the Jews.
[Acts9:19 And when he had received meat, he was strengthened. Then was Saul certain days with the disciples which were at Damascus. 20 And straightway he preached Christ in the synagogues, that he is the Son of God.
[1Cor12:12 For as the body is one, and hath many members, and all the members of that one body, being many, are one body: so also is Christ. 13 For by one Spirit are we all baptized into one body, whether we be Jews or Gentiles, whether we be bond or free; and have been all made to drink into one Spirit.]k
[Acts13:37 But he, whom God raised again, saw no corruption. 38 Be it known unto you therefore, men and brethren, that through this man is preached unto you the forgiveness of sins: 39 And by him all that believe are justified from all things, from which ye could not be justified by the law of Moses. 40 Beware therefore, lest that come upon you, which is spoken of in the prophets; 41 Behold, ye despisers, and wonder, and perish: for I work a work in your days, a work which ye shall in no wise believe, though a man declare it unto you. 42 And when the Jews were gone out of the synagogue, the Gentiles besought that these words might be preached to them the next sabbath. 43 Now when the congregation was broken up, many of the Jews and religious proselytes followed Paul and Barnabas: who, speaking to them, persuaded them to continue in the grace of God.44 And the next sabbath day came almost the whole city together to hear the word of God.]k
Paul preached in verse 38 forgiveness of sins and justification, to both Jews and Gentles. In verse 43 Jews were persuaded to continue in the grace of God.
[Acts15:10 Now therefore why tempt ye God, to put a yoke upon the neck of the disciples, which neither our fathers nor we were able to bear? 11 But we believe that through the grace of the Lord Jesus Christ we shall be saved, even as they. 12 Then all the multitude kept silence, and gave audience to Barnabas and Paul, declaring what miracles and wonders God had wrought among the Gentiles by them.]k
Notice at the first Church Council in Acts15 what Peter said in verse 11. He seems to believe both Jew and Gentle are saved by grace, not of works. Same gospel as Paul. Same gospel preached by all the apostles and Paul to both Jew and Greek=Gentiles
[Acts15:10 But by the grace of God I am what I am: and his grace which was bestowed upon me was not in vain; but I laboured more abundantly than they all: yet not I, but the grace of God which was with me. 11 Therefore whether it were I or they, so we preach, and so ye believed.]
Paul tells us all, other apostles, preach the same gospel of Jesus Christ.
