'Blameless' in the Bible

so that you may approve the things that are excellent, in order to be sincere and blameless until the day of Christ;

so that you will prove yourselves to be blameless and innocent, children of God above reproach in the midst of a crooked and perverse generation, among whom you appear as lights in the world,

as to zeal, a persecutor of the church; as to the righteousness which is in the Law, found blameless.
