Considering that Jesus followers for the past two millennia have been doing what Jesus said and it's been working great, your statements just raise the question of whether you just don't get it.
Jesus was quite clear that there's all kinds of false beliefs, teachers, prophets and ideas promoted in his name which will not result in your knowing him.
He was quite clear that we're to be on guard against false teachers.
Much of the bible talks about how people would miss it.
So, your ongoing attempts to discredit biblical christianity isn't helping your cause here.
