This warning is repeated several times. Seducers, with their scientific problems, were to be guarded against more carefully than any other peril that they would meet; for the entrance of these seductive spirits meant the entrance of the specious errors that Satan has ingeniously prepared to dim the spiritual perceptions of those who have had but little experience in the workings of the Holy Spirit, and of those who remain satisfied with a very limited spiritual knowledge. The effort of seducers has been to undermine confidence in the truth of God and to make it impossible to distinguish truth from error. Wonderfully pleasing, fanciful, scientific problems are introduced and urged upon the attention of the unwary; and unless believers are on their guard, the enemy, disguised as an angel of light, will lead them into false paths.... {Ev 359.3}

Denne advarsel blev gentaget flere gange. Der skulle passes mere på forførerne, og deres videnskabelige problemer, end nogen anden fare, som de ville møde; for når disse bedrageriske ånder kommer ind, kommer de besnærende vildfarelser ind, som Satan har beredt så sindrigt for at omtåge deres åndelige begrebsopfattelse som kun har en lille erfaring med Helligåndens virke, og for dem som stiller sig tilfreds med en meget begrænset åndeligt kundskab. Forførernes anstrengelser er at underminere tilliden til Guds sandhed og gøre det umuligt at skelne sandhed fra vildfarelse. Forunderligt tiltalende, fantasifulde og videnskabelige problemer bliver introduceret og drager den uforsigtiges opmærksomhed; og hvis de troende ikke er på vagt, vil fjenden, iklædt som en lysets engel, lede dem ind på falske stier. . . . .
