Things change, or they die.

I'm a different person from the one I was yesterday. As the sun rises, fresh and new light shines down and then we wake, renewed. We all change, every minute of everyday. Things recycle themselves, starting fresh and new. We learn new things, new experiences effect who we are. If we didn't, how on earth could we progress? We would be stuck, stagnant and unchangeable. But no, we are each able to grasp onto the atonement and let change fill our souls, turning over and moving forward. If there wasn't change we wouldn't have the potential to become like God because we couldn't repent, we'd be stuck, imperfect beings. Looking forward, not back is key to progression. We must learn and move forward continually.
