Q.1 Why did the people mutter: ‘He has gone to be guest of sinners.’
I think besides the self-righteousness that Seeker mentioned, it was also out of disdain. Because they were too self-righteous & hence proud to do such a thing, it totally must have begin "beneath them". Hence it must have been a sort of terrible shock.
Seeker: The real question is when did I first find Jesus? I believe that He is always there, but it is I who ignore Him.
Absolutely. Though Jesus lived in me since my infant baptism, I only had a personal encounter with Him in 1996 March. Even so, there were countless times before that, that I felt His Presence and His Protection and His love before getting to know Him personally.
Q.3 What changes did it bring ?
Tremendous! I think it first changed the way I thought (ala Romans 12:2) and everything moved from there. Am still learning and hence still changing in many ways.
