'Precious' in the Bible

The sorrow comes in order that the testing of your faith--being more precious than that of gold, which perishes and yet is proved by fire--may be found to result in praise and glory and honour at the re-appearing of Jesus Christ.

but with the precious blood of Christ--as of an unblemished and spotless lamb.

Instead of that, it should be a new nature within--the imperishable ornament of a gentle and peaceful spirit, which is indeed precious in the sight of God.
