Notice that he covers the possibility that no one will listen to his disciples in that entire town. During those times, as still true today, the message of love for God is not so attractive to many. This is because most of us don't want to accept someone else's greatness. We think we are the greatest.
And we want to be in control. We and want to be the master. We might believe in God only if He serves us. So we pray to Him only when we want stuff - as if God is our servant.
Here also we see the empowerment of Jesus' teachings. If someone rejected those teachings, it was their loss. This is the situation with every messenger who has been empowered by God to pass on these teachings. We have the choice to accept them or not. No one is forced to turn to the Supreme Being and give their love to Him.
This is the nature of love. Love requires freedom. So the Supreme Being gave each of us the freedom to love Him or not. Those of us who chose not to love Him were sent to the physical world and given temporary physical bodies to allow us the illusion of getting away from Him and acting independently.
We can also see from his statements that Jesus was not trying to elevate his position of being everyone's “personal savior.” Jesus’ life was focused upon teaching a particular message. While many in the Christian world today focus upon Jesus’ crucifixion, and Jesus' "dying for their sins," Jesus’ focus was the information - the message he was teaching. The instructions he was giving us, conveyed from the Supreme Being.
From Jesus' statement, we can see that the teachings of Jesus have the power to save us.
Those empowered by councils of men - deacons, bishops or whatever - are not given this power and authority. Why? Because a political appointment by men into a position of teacher, priest, minister or reverend makes that person a representative of men. Not a representative of the Supreme Being.
We can see from scripture what the authorized process is. We can see that Jesus was personally baptized by John the Baptist. We can see that Jesus' disciples were personally taught by Jesus and then asked to go out and spread those teachings.
From these events we can see how empowerment actually works: It works from a foundation of relationship - devoting oneself to the teachings of the representative of God. The student must establish a devotional relationship with, and take instruction from a living teacher - one who himself had a devotional relationship with and took instruction from a teacher.
Institutions cannot replace these personal relationships. Why? Because the Supreme Being is ultimately a person. And the Person of the Supreme Being must be introduced.
An institution cannot replace this introduction process.
This doesn't mean that a person has to have close physical contact with such a teacher. But a person must hear the personal teachings of the teacher, and must follow those teachings.
This process has been repeated over and over in the scriptures, when Joshua followed Moses. When Samuel followed Eli. When David followed Samuel. And when Jesus' disciples followed Jesus.
And what is the teaching being passed on? As both Moses and Jesus taught, and every other true representative of the Supreme Being has taught, it is about having a relationship with the Supreme Being:
" 'Love the Lord your God with all your heart and with all your soul and with all your mind.' This is the first and greatest commandment." (Matt. 22:37-38 and Deut. 6:5)
