People tend to discriminate against others according to their personal standards and preferences. They also tend to give advantage to those they like and hinder those they don’t like. Our God the Creator causes His sun to rise on the evil and the good and sends rain on the righteous and the unrighteous alike (Matthew 5:45). With the heart that resembles this heart of God you can live in peace. You can serve everyone and deal with anyone. You’ll become a great man who takes anyone under his wings and receives love among men.
