There are a couple times where Jesus says something like “the last shall be first, and the first shall be last” (Matthew 20:16). There are also times where Jesus mentions levels of responsibility, like the parable of the Talents (Matthew 25:14-29). He also talks about greatness in the kingdom of God, and being greatest (Matthew 18:1-6).
For most of my life, I just assumed that everyone was equal in heaven. You either get there, or you don’t. But now in reading the gospels again, I’m starting to wonder more about heaven. Will people have different levels of rewards? Will there be a level of greatness depending on how you lived your life?
