Not every unbeliever will be judged as severely as others. In Revelation chapter 20, the Apostle John tells us that it is by what we have done that we are judged. We saw those books—those books are important. Some have committed more sins than others, some have committed worse sins than others, and that will be recorded in the books and taken into account. Every work will be paid attention to.
However, that does not mean that those who are being judged could ever outdo themselves or do enough good works to outweigh their bad works. That is not the case at all; that is not the reality of humanity. As the apostle John tells us in chapter 3 of his gospel, the key issue is whether you believed in the name of the only Son of God. That’s the key thing, and everything else that you do is judged in light of that.
On the other hand, we must also remember the fact that there will be degrees of punishment. We know that because the devil is the one who is going to be punished most severely, but hear this: all who reject Christ will be punished eternally.
Yes, not everyone is as bad as each other, and not every sin is as bad as another, but that should not be a source of comfort for us. In fact, if anything, it should make us all the more fearful when we consider how we deserve to be treated on the day of judgement. The fact that you’re reading this from a church website condemns you all the more. As the apostle Paul spoke of himself, he said he was the worst of sinners, and he knew that because he was in the church. He knew the truth, and yet, even though he knew the truth, he still rejected Christ. It’s the same for us. There is no comfort in there being degrees of punishment for us personally.
The only comfort is Christ, and we must all repent from our sins as we trust in him and in his finished work on the cross.
