'Gospel' in the Bible

I am astonished that you are turning away so quickly from the one who called you by the grace of Christ to a different gospel,

not that [there] is a different [gospel], except there are some who are disturbing you and wanting to distort the gospel of Christ.

But even if we or an angel from heaven should proclaim a gospel to you contrary to what we proclaimed to you, let him be accursed!

As we said before, and now I say again, if anyone is proclaiming a gospel [to] you contrary to what you have received, let him be accursed!

For I make known to you, brothers, the gospel that has been proclaimed by me, that it is not {of human origin}.

to reveal his Son in me in order that I would proclaim the gospel [about] him among the Gentiles, immediately I did not consult with flesh and blood,

Now I went up [there] because of a revelation and laid out to them the gospel that I preach among the Gentiles, but in private to the influential people, lest somehow I was running, or had run, in vain.

to whom not even for an hour did we yield in subjection, in order that the truth of the gospel might remain continually with you.

But these, [when they] saw that I had been entrusted [with] the gospel to the uncircumcision, just as Peter to the circumcision

But when I saw that they were not being straightforward with the truth of the gospel, I said to Cephas in the presence of [them] all, "If you, [although you] are a Jew, live like a Gentile and not like a Jew, how can you try to compel the Gentiles to live like Jews?"

But you know that because of an illness of the flesh I proclaimed the gospel to you the first time.
