'Blameless' in the Bible

so that you may approve what is superior, in order that you may be sincere and blameless in the day of Christ,

in order that you may become blameless and innocent, children of God without fault in the midst of a crooked and perverted generation, among whom you shine as stars in the world,

according to zeal persecuting the church, according to the righteousness in the law being blameless.
