How do we know that Jesus changed the worship practices?

In John 4:21, Jesus explicitly states that the time will come when worship will no longer be confined to a specific location, such as the mountain in Samaria or Jerusalem. This statement reflects a paradigm shift in worship practices that was fulfilled in the New Testament. With Christ’s coming, the Old Testament ceremonial law and the sacrificial system, which were shadows and types pointing to Him, were no longer necessary. His life, death, and resurrection fundamentally changed the approach to worship, emphasizing a personal, direct relationship with God rather than ritualistic practices based on geography or cultural traditions.
