Quotes get reworded as they travel. Paste one below and this will tell you whether it appears in her writings word for word, whether the wording has drifted, or whether it cannot be found at all.
The passage you paste is searched against the Ellen G. White writings indexed by this site — books, compilations, manuscript releases, pamphlets, periodical articles, and letters.
A verdict of verified is only given when your text appears in a document exactly, ignoring nothing but capitalisation, curly quotes, and dashes, which change as text is copied between websites. Nothing is reported as genuine on the strength of a resemblance.
Most quotes that circulate incorrectly are distortions of something she really wrote. When the wording does not match but a long stretch of it does, the passage as published is shown next to it, so you can see exactly what changed.
It means the passage is not in the writings this tool searches. It is not proof that she never wrote the words anywhere, and a quote given to you with a reference may still be worth checking against that reference directly.
