You know why men test gold, why they put it in the fire. They know that if it is gold, fire will not hurt it. Men do not seek to destroy gold with fire. They do not seek to harm it in any way. Instead, they try to prove beyond all doubt that it is gold. And that is what God is doing when He applies the yardstick of His Word to His people. He seeks to show them, and the world, that they are true Christians.
