You mean you have blind faith in them.
Very weak and specious reasoning.
His self penned works are verifiable. They are among very few surviving from the time and as i said referenced as being by him from the 4th C. His oldest surviving texts in Greek are from the 10thC and Latin from the 5thC. And there is no reasonable reason to doubt that he was not real as the human qualities of the author are never contradicted. He is not claiming anything about himself that would qualify as supernatural or impossible. His works, his self penned autobiography and reference to him and his works by others from antiquity. It can't be a perfect record but blind faith does not apply. The nearest contemporary mention of Jesus is heresay by Josephus of his death by Pilate some 40 years after and it is acknowledging the supernatural element. However the possibility that the passage referencing Jesus is a fake and inserted in later translations is a contested topic.
