“Only in his home town and in his own house is a prophet without honor.” (Matthew 13:57)

Jesus made this statement under these circumstances:
When Jesus had finished these parables, he moved on from there. Coming to his home town he began teaching the people in their synagogue, and they were amazed. Where did this man get this wisdom and these miraculous powers? They asked. Isn’t this the carpenter’s son? Isn’t this mother’s name Mary, and aren’t his brothers James, Joseph, Simon and Judas? Aren’t all his sisters with us? Where then did this man get all these things?” And they took offense at him. (Matt. 53-57)
The offensive behavior of those who were seeing Jesus as a normal person was due to their enviousness. They wanted to bring Jesus down to their position - because they could not accept that someone was greater than themselves.

This describes how a person can easily become offensive with regard to the representative of God - and thus offend the Supreme Being. While we each have physical bodies, and the loving servant and representative of God may also have a physical body (though that body is actually spiritualized by their service to God), to compare the representative of God to a normal person is to commit a grave offense. Jesus describes the "prophet without honor," as offensiveness against the representative of God by those who see them as an ordinary person.

As mentioned, this typically takes place because of envy. Seeing the representative of God as a normal person takes place when a person wants what others have. They want to be the center of attention. They want the attention of others, and they are jealous when they see others having that attention.

This might be compared to an elephant stomping around a garden, destroying the various vegetables in the garden. Envy is has few bounds and it will easily encroach into the region where love for the Supreme Being is being practiced.

Spiritual growth might be compared to the fragile vegetables in a garden because growing spiritually is a fragile thing. We currently are full of self-centeredness, as this is our disease, and this is why we’ve fallen to the physical world and have taken on these temporary physical bodies within this hellish physical world.

The purpose of Jesus was to save those around him. He came to teach others about the Supreme Being and how we can be saved from the pit of hell - founded upon our self-centeredness.

To consider Jesus as a normal person - as we also find among secular and ecclesiastical institutions and their teachers - is to commit a grave error.

Consider for a moment if you sent a friend to deliver something to someone, and the intended receiver refused to accept your friend, started calling him names and even abused him or harmed him. How would you feel? You would feel pretty offended that such a person did this to your friend, wouldn't you?

This is how the Supreme Being feels when we offend Jesus or any of His loving servants - "a prophet" as Jesus mentions. Why? Because they are carrying out the Supreme Being's will. They are delivering a message on His behalf. As such, God's representative should be honored just as the Supreme Being would be honored - just as an ambassador is honored as a representative of his country.

To reduce or compare Jesus or any other representative of God to a common person is to commit a grave offense that can block and deter our spiritual progress.
