"Things that are different are not the same" goes for the Gentiles to whom Paul was first sent and those to whom he was later sent.
Paul wasn't sent to two different kinds of Gentiles. Paul was sent to Jews and Gentiles.
Yes, those to whom Paul was first sent became members of the one Body with the Gentiles to whom he was later sent, but some Gentiles (called Greeks in a KJB) got to hear the gospel of Christ preached to them because they were found in the synagogue of the Jews fearing God (Acts 13:16 KJV, Acts 13:26 KJV) and seeking a blessing according to the promise of Genesis 12:3 KJV (Galatians 3:29 KJV).
What a confusion you speak.
Paul plainly says that it is to THOSE Gentiles, those God fearing Gentiles, AND who he himself used to live like those who lived among those who lived to please their flesh.
Paul was among the ranks of the CUT OFF Jews.
Ephesians 2:3 All of us also lived among them at one time, gratifying the cravings of our flesh and following its desires and thoughts. Like the rest, we were by nature deserving of wrath.
No, they did not know that their blessing would come in the form of a mystery/the preaching of the forgiveness of sins (Acts 13:38-39 KJV)/ that Christ died for their sins, was buried and rose again the third day for their justification(Romans 4:25 KJV, 1 Corinthians 2:6-8 KJV, Romans 16:25-27 KJV. 1 Corinthians 15:1-4 KJV).
According to your confusion, all those who cursed Abraham receive the same blessing as those who blessed Abraham.
Why won't you just accept the deep mystery revealed that it is one gospel for all?
We can try all day long, but we cannot say the same thing about the Ephesian Gentiles to whom Paul wrote the letter. The "you Gentiles" that Paul became a prisoner of Jesus Christ for (Ephesians 3:1 KJV) in time past were without Christ, being aliens from the commonwealth of Israel, and strangers from the covenants of promise, having no hope, and without God in the world. These Gentiles were not found fearing God and seeking a blessing through Israel! They were worshiping the goddess Diana as late as Acts 19 (Acts 19:28 KJV)!
...and yet, they had a heart right enough to come into the light and be saved.
John 3:21 But whoever lives by the truth comes into the light, so that it may be seen plainly that what they have done has been done in the sight of God.
They are the people who are more spiritual than those who live only to please their flesh.
They are the people who hear about the message that saves everyone who repents of their sins.
We, by extension are just like these Gentiles (like the Ephesians to whom Paul wrote the letter) as we didn't have anything to do with Israel! There was no Israel by the time we came around!
This is where we fit in to God's mystery plan, beloved! It was unsearchable/hid in God that we should be fellowheirs with them and of the same Body beginning with Paul (on the same ship/the fellowship of the mystery) and partakers of God's promise in Christ BY THE GOSPEL (1 Corinthians 15:1-4 KJV) until the dispensation of the grace of God was given by God to Paul to usward!
ALL had to go through Jesus' blood---even those Jews who ALREADY belonged to God before Jesus came to earth.
John 17:6 "I have revealed you to those whom you gave me out of the world. They were yours; you gave them to me and they have obeyed your word.
JESUS EVEN went to prison/hell---to preach to the people who were so wicked and evil in the days of Noah.
Jesus preached the one and only gospel that saves, even to them!
To them, to those who you claim did NOT yet have the gospel that saves as Paul was later given!
There were those who disobeyed and died before Jesus came to earth, though they were dead their spirits went to a prison, unlike the spirits of the righteous. After Jesus was crucified, he preached to those who were dead, he preached to the spirits in prison, the spirits of those who had died and disobeyed long ago (see 1 Peter 3:18-19). Those people who disobeyed and died before learning of Jesus...Jesus preached the gospel to them, so that they might be judged according to men in regard to the body, but live according to God in regard to the spirit (1 Peter 4:5-6). For Christ died for sins once for all, the righteous for the unrighteous, to bring us to God, even those who lived and died before Jesus.
