Sounds like we who came out of the nations are to especially heed the words of Paul which he received from Christ:
1Th 2:13 For this cause also thank we God without ceasing, because, when ye received the word of God which ye heard of us, ye received it not as the word of men, but as it is in truth, the word of God, which effectually worketh also in you that believe.
1Th 1:5 For our gospel came not unto you in word only, but also in power, and in the Holy Ghost, and in much assurance; as ye know what manner of men we were among you for your sake.
1Th 1:6 And ye became followers of us, and of the Lord, having received the word in much affliction, with joy of the Holy Ghost:
1Ti 2:7 Whereunto I am ordained a preacher, and an apostle, (I speak the truth in Christ, and lie not, a teacher of the Gentiles in faith and verity.
2Ti 1:11 Whereunto I am appointed a preacher, and an apostle, and a teacher of the Gentiles.
2Ti 1:13 Hold fast the form of sound words, which thou hast heard of me, in faith and love which is in Christ Jesus.
Rom 15:18 For I will not dare to speak of any of those things which Christ hath not wrought by me, to make the Gentiles obedient, by word and deed,
1Co 11:1 Be ye followers of me, even as I also am of Christ.
Rom 11:13 For I speak to you Gentiles, inasmuch as I am the apostle of the Gentiles, I magnify mine office:
Steko, I understand that "some" of What Jesus taught was for Israel but much if not most of what Jesus taught was for "everyone" both Jew and gentile.
Great deception and confusion arises when folks take all of Jesus' teachings and dismisses them as to Israel only.
The verses you quoted show plainly that Paul was not the only one that preached the Gospel of grace.
1Th 2:13 For this cause also thank we God without ceasing, because, when ye received the word of God
which ye heard of us, ye received it not as the word of men, but as it is in truth, the word of God, which effectually worketh also in you that believe.
1Th 1:5 For
our gospel came not unto you in word only, but also in power, and in the Holy Ghost, and in much assurance; as ye know what manner of men we were among you for your sake.
Exactly how does one follow Jesus when they don't believe what He taught was for them ?
1Co 11:1 Be ye followers of me, even as I also am of Christ.
Paul pointed others to Jesus who he himself followed. If all of Jesus' teachings were for Israel how exactly are you going to follow Him, and why would Paul if he brought something no one else had previously believed about Jesus direct everyone else to follow Jesus ? Then comes along some and designates everything Jesus taught as being for Israel.
See the problem yet ?
The following Jesus taught was for everyone,but yet if I were to believe much of what I have heard here at TOL what Jesus taught would be relegated to Israel only, and that is not the truth.
Jhn 14:1
Let not your heart be troubled: ye believe in God, believe also in me.
Jhn 14:2
In my Father's house are many mansions: if it were not so, I would have told you. I go to prepare a place for you.
Jhn 14:3
And if I go and prepare a place for you, I will come again, and receive you unto myself; that where I am, there ye may be also.
Jhn 14:4
nd whither I go ye know, and the way ye know.
