Does Christianity claims that congenital deaf-blindness could never be cured by humans?

I am not a christian so please forgive me if there maybe a lack of knowledge from my side about it in the question. If I say that I am a son of god (God forbid) , then no christian will believe me. But they believe Jesus to be so. This is because there's special distinction between a normal person like me and Jesus. Moreover, it's not any wise to listen any normal person blindly and believe him. So, the Jesus was different from normal persons, and his miracles proved it. One of his miracles was to heal people who were deaf/blind from their birth. So, **preserving the un-ambiguity and distinction of Jesus, does Christianity claims that humans will never be able to cure congenital deafness/blindness ** ?
