Noah and God's grace

[jeff]

I’m currently taking our Sunday School class through Genesis. We are up to the point of the flood, and we discussed Sunday about Noah finding grace in God’s eyes and being obedient. I can find nowhere in Scripture that says that Noah’s family was found righteous. They were allowed on the ark, and obviously God had a purpose for them being there, but were they allowed on because of Noah, because of their own merit, or simply because God wanted them there?

One might make the assumption that they were not wicked like the rest of the world, but I can’t find anywhere in the Bible that says that. Or am I missing something?

Thanks for the help!!
