The term "blameless" literally means "without blame." It is used to refer to a person who obeys God wholeheartedly, but it does not mean that the person is sinless.
* Abraham and Noah were considered blameless before God.
* A person who has a reputation for being "blameless" behaves in a way that honors God.
* According to one verse, a person who is blameless is "one who fears God and turns away from evil."
