The continuity of the gospel is all about sharing and passing on what you received.
Paul says, “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,”
Although we have the obligation of sharing the gospel the way we received it, the most important thing is to share it according to scriptures.
We have had men preach the gospel with zeal but outside of scripture. If any word is preached outside of scripture then it is not Christ centered who is the Word.
Paul even goes on to say that even if an angel preaches to you any word besides what He gave, let the angel be accursed.
All the gospel, all revelation, all conviction should be based on scripture.
