One, she is one of the few women in the Old Testament who speaks, whose words have been recorded. And two, she had faith.
After she and Adam were kicked out of the Garden of Eden, Scripture records two things she said.
In Genesis 4:1 she says, "'I have gotten a manchild with the help of the LORD.'"
Then in Genesis 4:25 she says, "'God has appointed me another offspring in place of Abel; for Cain killed him.'"
There was at least 130 years between those two verses, maybe more. She kept her faith. God was a huge part of her life. Her eyes were on God.
