One of the things, Jesus was sure of was where He had come from and where He was going. The Pharisees challenged Him on many occasions but they never stirred His existence nor could they change Him. He not only told them who He was, but He demonstrated it before them. Jesus knew His end from the beginning. When you become a child of God and understand the new family dynamics in the heavenly realm of which you belong, then no one or nothing will move you.
