Treasury of Scripture Knowledge
Upon [hearing] this, many of Jesus' disciples turned back and refused to accompany Him anymore. [Note: They deserted Jesus physically as well as spiritually].
Then Jesus said to those Jews who had believed [in Him], "If you people continue [obeying] my message, then you are truly my disciples.
So the Jews, [who were assembled in the synagogue. See verse 59] began complaining about Jesus because He had said, "I am the bread that came down from heaven."
Why do you people not understand what I am saying? It is because you cannot [bear to] listen to my message.
The person who does not find an occasion for having doubts about my identity is fortunate indeed."
[Now] we have many things to say about Melchizedek, but because of your slowness to grasp things, they are hard to explain.
2 Peter 3:16
He spoke about these things in all of his letters, which contain some parts that are difficult to understand. [Because of this], ignorant and unstable people twist [his writings], just as they also do to the other Scriptures, to their own destruction.
