Each person that has ever lived on earth will be judged in their appointed time. The Christ, the one who taught us about the Plan and gave us the perfect example of following it, will be our judge. His judgment will be based on how diligently we followed his example and became the people he hoped we would become. When you did something wrong but then repented for it, the Christ will not consider those mistakes in his judgment.
We will be resurrected and after we are judged, we will be given our reward. Basically, there are three rewards that we receive, based on how we made use of the Plan.
The ‘E’ symbolizes the judgment that each of us must eventually pass through. The three arms of the symbol represent the three basic rewards we can receive based on our efforts in following the Plan.
