Here is the gospel:
1 Corinthians 15:
1 Moreover, brethren, I declare unto you the gospel which I preached unto you, which also ye have received, and wherein ye stand;
2 By which also ye are saved, if ye keep in memory what I preached unto you, unless ye have believed in vain.
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;
4 And that he was buried, and that he rose again the third day according to the scriptures
That is what Paul taught them.
If that were the Gospel then why did you leave out all of what Paul said.
For I delivered to you first of all that which I also received: that Christ died for our sins according to the Scriptures, and that He was buried, and that He rose again the third day according to the Scriptures,
and that He was seen by Cephas, then by the twelve.
After that He was seen by over five hundred brethren at once, of whom the greater part remain to the present, but some have fallen asleep.
After that He was seen by James, then by all the apostles.
Then last of all He was seen by me also, as by one born out of due time. 1 Corinthians 15:3-7
Do you ever see anyone in the Bible preaching all that.
The Gospel of the Lord Jesus Christ is:
Repent for the kingdom of God is at hand.
That’s what the Apostles preached.
That what He sent Paul to preach.
So I said, ‘Who are You, Lord?’ And He said, ‘I am Jesus, whom you are persecuting. But rise and stand on your feet; for I have appeared to you for this purpose, to make you a minister and a witness both of the things which you have seen and of the things which I will yet reveal to you. I will deliver you from the Jewish people, as well as from the Gentiles, to whom I now send you, to open their eyes, in order to turn them from darkness to light, and from the power of Satan to God, that they may receive forgiveness of sins and an inheritance among those who are sanctified by faith in Me.’
“Therefore, King Agrippa, I was not disobedient to the heavenly vision,
but declared first to those in Damascus and in Jerusalem, and throughout all the region of Judea, and then to the Gentiles, that they should repent, turn to God, and do works befitting repentance.
Acts 26:15-20
to whom I now send you, to open their eyes,
in order to turn them from darkness to light, and from the power of Satan to God, that they may receive forgiveness of sins
Therefore, King Agrippa, I was not disobedient to the heavenly vision,
but declared first to those in Damascus and in Jerusalem, and throughout all the region of Judea, and then to the Gentiles,
that they should repent, turn to God, and do works befitting repentance.
