Some people like new things. New shoes, a new car, etc. Some like the things they are familiar with, like well-worn shoes and a reliable, albeit old, car. Jesus came bringing a lot of “newness” in how faith was expressed toward God and in the name of God. Some received this with joy, others felt something was being lost and resented it.
Mark 2:21-22 21 "No one sews a patch of unshrunk cloth on an old garment. If he does, the new piece will pull away from the old, making the tear worse. 22 And no one pours new wine into old wineskins. If he does, the wine will burst the skins, and both the wine and the wineskins will be ruined. No, he pours new wine into new wineskins."
