My commands haven't changed since I brought your ancestors out of Egypt, a nation that seemed like a blazing furnace where iron ore is melted. I told your ancestors that if they obeyed my commands, I would be their God, and they would be my people.
I will separate the sinful rebels from the rest of you, and even though I will bring them from the nations where they live in exile, they won't be allowed to return to Israel. Then you will know that I am the LORD.
Your faith will be like gold that has been tested in a fire. And these trials will prove that your faith is worth much more than gold that can be destroyed. They will show that you will be given praise and honour and glory when Jesus Christ returns.
