“Every man's work shall be made manifest: for the day shall declare it, because it shall be revealed by fire; and the fire shall try every man's work of what sort it is.”
King James Version (KJV)
3:13 The time is coming when every one's work shall be made manifest: for the day of the Lord, that great and final day, shall declare it - To all the world. For it is revealed - What faith beholds as so certain and so near is spoken of as already present. By fire; yea, the fire shall try every one's work, of what sort it is - The strict process of that day will try every man's doctrines, whether they come up to the scripture standard or not. Here is a plain allusion to the flaming light and consuming heat of the general conflagration. But the expression, when applied to the trying of doctrines, and consuming those that are wrong, is evidently figurative; because no material fire can have such an effect on what is of a moral nature. And therefore it is added, he who builds wood, hay, or stubble, shall be saved as through the fire - Or, as narrowly as a man escapes through the fire, when his house is all in flames about him. This text, then, is so far from establishing the Romish purgatory, that it utterly overthrows it. For the fire here mentioned does not exist till the day of judgment: therefore, if this be the fire of purgatory, it follows that purgatory does not exist before the day of judgment.
1Co 3:13 Every man's work shall be made manifest. The kind of work that every builder does will be made known. The day shall declare it. Probably the day of Christ's coming. Because it shall be revealed by fire. As fire destroys wood, hay, stubble, but leaves gold, silver, precious stones (see 1Co 3:12), so the work of some builders, when tested, will vanish. They do not do solid work.
