The refining pot is for silver and the furnace for gold,
But the LORD tests hearts.
The Lord tests our hearts as to make our faith into silver and gold – to refine it and remove it of it’s defiled and expendable additions. It is a glorious extracting process.
True virtue never appears so lovely, as when it is most oppressed… [trials] purify and increase it. They not only manifest it to be true, but also tend to refine it, and deliver it from that which is false, which encumber and impede it, that nothing may be left but which is true.
Jonathan Edwards – Religious Affections
