From the story in John 21 and D&C 7
"Our perfect, loving God makes no horizontal comparisons in this story. In this verse, Jesus only compared John with John's former self, John with old John. He only compares Peter with old Peter, former Peter. He only compares me with old me."
comparisons "can fuel envying and coveting or self-loathing and the paralysis of inaction can really be just that debilitating can keep us from play the vital role that has been allotted to us."
