Remember how the LORD your God led you all the way these 40 years in the desert, to humble and test you in order to make known what was in your heart, whether or not you would keep his commands.

let my righteousness be weighed in honest scales, and God will make known my integrity.

The crucible is for silver and the furnace for gold but the LORD assays hearts.

And I will bring that surviving third through, testing them as if through fire, purifying them like silver, assaying them like gold. They will call on my name, and I will answer them. I will say, "This is my people,' and they will say, "The LORD is my God.'"

But who will survive the day when he comes? Or who can stand when he appears? Because he's like a refiner's fire and a launderer's soap,

so that your genuine faith, which is more valuable than gold that perishes when tested by fire, may result in praise, glory, and honor when Jesus, the Messiah, is revealed.
