Philippians 2:15

so that you may be blameless and pure, children of God without fault in a crooked and perverse generation, in which you shine as lights in the world

Note Deuteronomy 32:5

That ye may be blameless and harmless, the sons of God, without rebuke, in the midst of a crooked and perverse nation, among whom ye shine as lights in the world;

that you may become blameless and harmless, children of God without defect in the middle of a crooked and perverse generation, among whom you are seen as lights in the world,

that ye may become blameless and harmless, children of God without blemish in the midst of a crooked and perverse generation, among whom ye are seen as lights in the world,
