'Faultless' in the Bible

so that you may be blameless and pure, children of God who are faultless in a crooked and perverted generation, among whom you shine like stars in the world.

But now He has reconciled you by His physical body through His death, to present you holy, faultless, and blameless before Him—

For if that first covenant had been faultless, there would have been no occasion for a second one.
