Notice that Jesus did not need the religious leaders or the political leaders. Jesus did not need religious or political leaders to support and validate who He was.
Matter of fact, Jesus did not hesitate to shine the light of truth on the hypocrisy of the religious leaders.
These religious leaders were more interested in preserving their position and influence than pursuing the truth.
They knew the truth would expose them and threatened their power and influence.
Instead of testing to verify whether or not Jesus was the Messiah, they spent all of their time looking for excuses not to believe in Him and for reasons to kill him.
In contrast, the false messiah will flatter religious and political leaders as he will need their support and validation. He will promise them increased power and influence if they will support him in a “scratch my back, and I’ll scratch yours” arrangement. He will appeal to them as an equal, and as a friend, then ultimately as their master. And like any abuser, he will dispose of them when they are no longer of use to him.
