Christ's discourse in the synagogue concerning the bread of life was the turning point in the history of Judas. He heard the words, "Except ye eat the flesh of the Son of man, and drink His blood, ye have no life in you." John 6:53. He saw that Christ was offering spiritual rather than worldly good. He regarded himself as farsighted, and thought he could see that Jesus would have no honor, and that He could bestow no high position upon His followers. He determined not to unite himself so closely to Christ but that he could draw away. He would watch. And he did watch.

Kristi tale i synagogen om livets brød blev til vendepunktet i Judas tilværelse. Han hørte disse ord: "Hvis I ikke spiser Menneskesønnens kød og drikker hans blod, har I ikke liv i jer." Joh. 6,53. Han indså, at det snarere var åndelige end verdslige goder, Kristus havde at tilbyde. Han betragtede sig selv som vidtskuende og mente at kunne se, at Jesus ikke ønskede sig nogen ære, og at han ikke ville være i stand til at give sine disciple høje stillinger. Han bestemte sig til ikke at knytte sig så fast til Kristus, at han ikke kunne trække sig tilbage. Han ville være på vagt, og han var på vagt.
