So, due to my first language being French, I got on google and typed gospel definition and got this:
gos·pel
ˈɡäspəl/
noun
1.

"it is the Church's mission to preach the gospel"
synonyms: Christian teaching, Christian doctrine, Christ's teaching; More

"they say it's sold out, but don't take that as gospel"

2.

Which leads me to think, the heck were you trying to say?
