When our apostle Paul received the gospel from Christ he went to the heathen in Arabia.
Gal 1:16 To reveal his Son in me, that I might preach him among the heathen; immediately I conferred not with flesh and blood:
Gal 1:17 Neither went I up to Jerusalem to them which were apostles before me; but I went into Arabia, and returned again unto Damascus.
We have limited information about how long and as to what the details are in those areas, but we do know that Paul obeyed the Lord Jesus Christ and preached the gospel in different regions.
The main problem when the gospel is preached is apposition, those who appose the preaching of the cross of Christ.
When Paul wrote to the Galatian church there was not only apposition but among them there were those who were been moved away from the gospel
Paul preached to another gospel.
Gal 1:6 I marvel that ye are so soon removed from him that called you into the grace of Christ unto another gospel:
Gal 1:7 Which is not another; but there be some that trouble you, and would pervert the gospel of Christ.
Gal 1:8 But though we, or an angel from heaven, preach any other gospel unto you than that which we have preached unto you, let him be accursed.
Gal 1:9 As we said before, so say I now again, If any man preach any other gospel unto you than that ye have received, let him be accursed.
Have you ever marvelled at the beauty of creation ? That same creator came from Heaven to this earth and died for our sins.
And that is the gospel I have believed; Christ died for our sins...
God was in Christ
2Co 5:19 To wit, that God was in Christ, reconciling the world unto himself, not imputing their trespasses unto them; and hath committed unto us the word of reconciliation.
What gospel are you trusting today for salvation ?
Paul says if someone comes, even and angel from heaven with another gospel, let them be accursed.
That is serious, because they will dam your souls with another gospel.
Folks it has to be the gospel given to Paul by Christ alone for your salvation ;
1Co 15:3 For I delivered unto you first of all that which I also received, how that Christ died for our sins according to the scriptures;
1Co 15:4 And that he was buried, and that he rose again the third day according to the scriptures:
