That's your claim but it's supported only by your opinion which carries no weight.
Let's be clear about one thing. That is a verse you are referring to. My point is drawing from Matt 19, specifically surrounding how the young ruler could possibly have known Jesus was referring to himself. Your distraction has nothing to do with my point.
Now, to your bloviation and irrelevant response, where, in any of that, did Jesus declare himself master? He was a teacher. Who sent him?
So much for reading it in context. Now read verse 20, "Very truly I tell you, whoever accepts anyone I send accepts me; and whoever accepts me accepts the one who sent me.”
Again, who sent Jesus? Who made Him their teacher?
The context is that if he, being their teacher, washed their feet then they would to wash one another's feet. That is not the action a master would take. Jesus, obviously, made himself one of them. He is, in fact, one of us. The spiritual head/leader who wants us to see him as being equal with us. His job, as he defined in here is to bring us to the one who sent him. The message is, Look, I have found the way. Come, follow me. If you will follow me, I will bring you to the one who sent me.
I'll ask again, who sent Jesus? Did he send himself? Is he his own Father?
