I don’t know about you, but I personally love this part of the redemptive phase, because the universalistic argument takes the seemingly worst part and transforms it into the best.
The sulfur is used for purification, along with the fire. To emphasize this point, Isaiah had a similar experience:
Who ever knew that God would use burning to redeem? Well it kinda makes sense, doesn’t it?
Now the really interesting part is that somehow this burning is still connected to the cross, since the cross is the gateway of the love of God to us and thus of our salvation…
