Revealing is not cleansing
No, by itself it is not. No one argued it is. Burning of stubble and hay, however, is cleansing as well as revealing, and yes, that is possible because Jesus died and rose again.
I think we are talking past each other here. Look at the definitions below.
Cleansing; To free from dirt, defilement, or guilt; purge or clean.
Reveal; To make known by supernatural or divine means
The definition of cleansing is to purge or clean. When most people hear the word purgatory it, to them, means that one is purged of their sins. The Bible teaches that when a person accepts Jesus as their savior they are washed clean of their sins through the shed blood of Jesus. In other words, no further cleansing is necessary. Jesus sacrifice was complete and final.
The passage we are talking about refers to revealing the works done which will last. Some works will not last because of impure intentions or error in theology or simple false doctrines. Upon ones death those works which do not last have simply been revealed.
So while you and I may be in agreement, I believe that too many people believe that some of their sins will be purged from them after death. By that I mean that they don’t understand that Jesus paid for those sins and they don’t carry those sins with them if they have asked for forgiveness.
