We know what is right, and we know that we fall short of that standard. There is a feeling that we have violated God's laws. We have missed the mark. This was the same question posed to Jesus, as recorded in Mark 10, when the man came up to Him. This question is about justification.
Justification has to do with justice being settled and finished.
There are several answers to this question. Some say that God automatically saves all people, and punishes none. In other words, there is no punishment. This is called universalism. Another answer is God will punish all people.
