So treat people with respect and they will treat you the same way. A starting point for good relationships is respect for other people because they are children of God.
Respect is the foundation of harmony in families and peace between nations.
The gospels are filled with stories of Jesus reaching out and respecting others. They are stories of love. Thus he forgave sins, healed the sick, and ate with outcasts and sinners. Jesus wanted to liberate people from whatever held them in bondage. He wanted everybody to be included in the kingdom of God.
