This is a very good passage of scripture which helps us to determine the validity of the faith of others and their ideologies. We can ask ourselves are they hearing the voice of Jesus when we compare their words with scripture.
Jesus does not tell one person one thing and another something different when using the same verse. God’s truth is the same for everyone. So when someone tries to re-translate a passage of scripture or claim that a verse says something different from it does we can guide our decisions to accept or reject their words with this phrase.
People who hear Jesus’ voice bring the truth and do not try to change God’s word to fit their desires
