That's a great question brother. I have not looked at it before but it makes sense to me as l believe in a three stage sanctification process. The refining is especially of interest to me as it occurs after the purifying and l believe it continues until death. I am sure that there are some spiritual gems to be had in a study of metalwork.

Commentary by Adam Clarke on this verseMany shall be purified - During the interim, the great work of God's providence and grace shall be carried on in the salvation of men; who, in the midst of trials, temptations, and difficulties, shall be purified and made white - be fully saved from their sins. None of the wicked shall understand - Because they are wicked, and will continue in their sins, the eyes of their understanding shall be closed, and their hearts hardened; so that they shall not see the light of the glorious Gospel. But the wise - Those who open their hearts to God, that he may pour in his light, shall understand the things that make for their peace.
