It's called cold reading. You start with a broad and likely claim, and if you get a hit ( based on looking at the persons reaction ) you start narrowing the scope. I'm not sure that comes from Jesus the Christ however.
You know, some Christian hucksters want your money. Some Christian hucksters want to lie you into being less of a shitheel. Some Christian hucksters want you to vote for someone so they can get political favors.
This Christian huckster wants to destroy your entire fucking life.
