"Treat others the way you want to be treated" seems easy enough, as long as those "others" are people we like/agree with/who share our views. But when we have different thoughts and opinions, we're quick to judge and get angry with one another and "cancel" those we don't get along with. God calls us to a standard of perfection, but He also teaches us how to show mercy to ourselves and to others when that standard isn't met. Jesus was the only "perfect dude" who ever lived, and He made a way for us to be perfect through His sacrifice for us.
