There is a human tendency to reminisce about "glory days". Looking back has pros and cons: it can teach lessons but can also be harmful if it leads to disobedience or dwelling on the past. The Bible contains many examples of the dangers of looking back, such as Lot's wife and Paul's exhortation to forget what is behind. True glory belongs to God. Our focus should be on the future and the hope of Christ's return. Hope and work, both physical and spiritual, can help us stay focused on the future and avoid dwelling on the past. Our glory days are not in the past, but in the future. We should purify ourselves and live in accordance with God's word.
