Of course, Christianity teaches no such thing, and we can only wonder why a youth pastor wouldn't understand basic Christian doctrine.
There is, however, a religion that does teach that God created human beings with sin. That religion, ironically, is Islam. Unfortunately, Yusha doesn't know enough about Christianity or Islam to realize that he's actually condemning Islam, not Christianity, when he mocks the claim that God created people with sin. By mocking the teachings of his own prophet, Yusha may have just apostatized!
