Jesus' biggest blunder was to perform miracles. The thing about persuading people with no faith by performing miracles is that after they've seen the miracle—say you command a disease out of their sick loved one—they are no longer as interested in learning how to work on their faith as they are in using you as a mass miracle manufacturing tool.
And the fascinating part is that Jesus himself actually seemed aware of this trap. If you read the Gospels closely, you catch moments where he is actively trying to suppress the spectacle. He heals people and then strictly orders them not to tell anyone. He escapes into the mountains when crowds try to forcefully elevate him after a mass feeding, and later rebukes them by pointing out they are only following him for a free meal, not to understand the teachings. He knew the miracles were breeding dependency.
This, by the way, is the reason why Christianity found its way into a religion. The gospel teachings are about empowering one to commune with one's god and less about organized religion. But perhaps worse than that, this Christian idea of waiting for the messiah kind of makes people wait for the second coming instead of doing the needed work right now to get to the right hand of the father.
So then we have this dichotomy of the conman preacher faking miracles, and the congregation that has lost all faith that it really needs the preacher's miracle to stay sane, even when most of them rightly suspect that the miracles are fake.
And it is this same Christian mindset that extends into politics where we all perform these election rituals and pretend that this leader is going to make things work because for some reason he is a better miracle maker than the previous one.
Yet in the end, you have to read the gospel for yourself and focus on working on your own faith until you can make the miracles yourself. Anything other than that is a performance of Christianity and has very little to do with the actual teachings of Jesus the Christ.
