Why Enoch? Why is Hebrews 11:6 connected to his example?

How did Noah condemn the world? How should we do likewise?

The New and Living Way | Episode 31 | Hebrews 11:5-7

By faith Enoch was translated that he should not see death; and he was not found, because God translated him: for he hath had witness borne to him that before his translation he had been well-pleasing unto God: and without faith it is impossible to be well-pleasing unto him; for he that cometh to God must believe that he is, and that he is a rewarder of them that seek after him.

By faith Noah, being warned of God concerning things not seen as yet, moved with godly fear, prepared an ark to the saving of his house; through which he condemned the world, and became heir of the righteousness which is according to faith.
