When you act with sincere heart and purpose, it’s like living out of the sweet spot of your character. You act from the very core or center of your being.
The principles or virtues the commandments promote work together. So they naturally overlap and complement each other. And if someone observes one or two, it’s more likely they’ll observe others as well. People of sincere heart and purpose act openly in the light. They act without manipulation or self-deception. They don’t hesitate to act in the light because they are of the light. And their goodness shines as a beckoning beacon to others.
Treating others badly is not only bad for you (because it reinforces dysfunctional thinking an behavior patterns) but it also enables the person who’s treated you poorly to feel justified in the unhealthy attitudes and behavior they’ve exhibited.
